Determine whether each statement is true or false. If the slopes of two lines are -1 and $1,$ then the lines are perpendicular.

When the lines who X plus three y squared off poor on the line three x minus. Why did support for, uh but it So let's check it. But a bendable. So we'll find a slope off the board lines on with multiply the So If it did you Quito minus one, then we can say that the lines are perpendicular. So first right in the slope intercept home. So the first we'll do that right in slow slope intercept from find slope. So if you say this is a prosthetic elation Second question So you find that three. Why Egypt minus two x less four and why it acquittal minus two by three X plus four by if, uh said slope I'm 16 onda plus again is a part of the equation. And four seconds if you want to write, this is are why magical? Do three x minus for you know why it's called a three by two x minus store. So say the slope is empty. See? No, the condition for two lines will be by the pain. Nicollette, what a looker. If If there slope Uh, I m one and m two. I am one AM Cho is equal to minus one. So far, they've given equation for given equation and one in tow. Temple, which is someone is given here. Say M one is minus two y three and and I'm looking fine from here. And this three way to cancel on three Americans which equal to minus one. So that that is condition the satisfying the conditions. So lines are but a friend of blood on this is fruit shipment.

So here we're looking at lying one containing the point to negative 56 and two. And then also the 20.82 negative to, um So I'm going to call this my coordinate one Huntsman coordinate to this makes six my X one and to my Y one. And then I have my ex, you and wide too. So I'm gonna use that to find this slope. So the slope relying one will be Why choose so negative two minus y one, which is to over x two, which is Pete's minus X one, which is six. So that gives us two minus or negative two minus two is negative for meat. Minus six is too. So that gives us negative to over one or just negative, too. Now I have a line to a swell, and those points are 51 That's one point. And then 30 is the accordance of another point. And I'm gonna call this 0.1 and 0.2 for P. And then for each of these, we can have an X one y one and x two y two. Okay, so let's find slope for that. So the slope for 12 will be. Why to which is zero minus y one, which is one for X to, um which is three minus X one, which is five. So I get negative one over. Negative two is even true. 1/2. And these are opposite reciprocal to each other. Negative two and positive 1/2 our officers. Sickles. So M one is perpendicular to but not him. No one is perpendicular to l two.

We need to determine the following statement is true. Were given the line two X plus three Y equals four and three x minus two. Y is equal to four are perpendicular. So first we need to rearrange these into slope intercept. So we're going to move this two X over and we get three Y is equal to negative two X plus four. You divide everything by three. Can we get Y is equal to negative two thirds X plus four thirds. So our slope is negative 2/3. You do the same thing for the second equation. So we subtract three X from both sides. We get negative two. Y is equal to negative three X plus four. We divide both sides by -2. We get Y is equal to positive three halves X minus two. So our slope is three halves. And so when we take our two slopes negative 2/3 And 3/2 and we multiply them together, we get negative six Over positive six and that's negative one. So when you multiply the two slopes and you get negative one, that shows that the two lines are perpendicular. So this is a true statement.

Hello. Workers are number 15 months. Here. We have to take the one points are timber disses off right under the Bangor 10.9. Common sticks minus one. Come on to kind of Come on. Minor street. First detect the slopes of these two point is everyone still going by through minus 60 by minus one minus nine with testicles Might ask four divided by my inner step, which is It goes to grew by five strope off the light Between these two points, M two equals minus three minus. Still there in like my last line, which is a close to minus five by boots. Therefore, every party you didn't like that live in Bangor. Don't be like this. That would be nine things. That would be my last line to this can be learned Ministry so used to par par printed blood. I have money going B minus one. You wanna do in country guys saying in the minus five? I do. We usually go to my Nesler. Yes, the things that right Dangler. They're back. Not even bother. Question. Thank you.
