Use a system of equations to solve each problem. See Example 8. Find an equation of the line $y=a x+b$ that passes through the points $(-2,1)$ and $(-1,-2)$.

I mean I want to find the equation of the line. Why he calls x. Class B which passes drew the points -2 and one Then -1-. So for the two points minus Drew for the first point is the value for X. And one is the value for Y. For the second point money's one is a value for eggs. A minus. True is the value for why for us to find Y equals X plus B. We know that A. Is the ingredients or the slope. So we are to find the slope which L will be given by while true minus Y. One over extra. My next extra which is it's equal to we have wise mutually. Mine is true. Then why I want to do one An extra is line as one And X one is -2. So we have minus minus true Preach This will result -3 over -1. Last Truth. So we have a to be called minus three over one Which is equal to three to read. So that's our slope. So then I sent me out to do is to find our one intercept which are y intercept. Come found using any of the points. So Let's use the first point which has X to the -2 and why? To be one. So substituting into Y equals X plus we have Why are you to be called one purchase the culture our gradients being equals to me X. To be called to mind. That's true then class B. We have one equals -6 plus B. Making the the subject. we have We to recall one plus six pitches people to set. So substituting into the main question how why to be called three X last seven? This is our equation off deadline.

So here is a problem. Looking at a system of linear equations on we previously found where they are intersecting. Um, and that was X equals four y equals two. And now we're checking those answers by plugging them into our equations and seeing if they give us the same answer. Um, we had our X equals four manner. Why equals two, um, finale. Put those into our equations. So we had negative X so negative for plus why? Which is to equals negative, too. And tu minus four is negative two. So that one works, and now we have to do it for another one. We take our two times X, which is four. And then we do, plus y a r y was, too. So we get two times four is eight plus two equals 10. So this equation also checks out. So we know that our solutions to this system of linear equations is, in fact, correct.

So we have the two equations here and we want to solve the system where we can start by doing solve for X on this situation here. So by adding to write each side me a excessive to two y minus seven, then we can plug in what we know for X into this equation here to be a Y minus X or to y by seven times. Why is you go to negative 10. So that means that why minus two y squared plus seven y is equal to negative 10 who bring everything toe one side we get that two y squared minus eight Y minus 10 is equal to zero. So if we divide everything by two, we have that why squared minus four y minus 500 You can factor this to get my minus five times one plus one. So that means that by is equal to five or why is you go to negative one Just you know the access equal to two y minus seven When wise eat toe five we got the X is equal to three and when y is equal to negative one X is equal to negative nine so our solutions have for this equate for the system of equations is requalify and a negative nine common negative blonde.

All this isn't on. The equations here will weaken. Step I do is about isolating. Why in both equations So we have wise he would attend minus sex And why is equal to 21 divided packs since 10 of minus sex and 21 over X? Is he goto are both equal to why we can equate come together? Well, the Bible sides by X and brain reading toe one side So we can a quadratic equation here, in fact, of this into X minus three next minus seven. So our solutions are when X is equal to three and when x is equal to seven Since we know that, why is he going to 10 minus X when x is equal to three y z seven and when exiting with seven y 0 to 3 for our final solutions?
