On week 16 of math 10 we’ve learned how to solve system of equations. To solve system
of equations you have to know how to graph them.
For example we have this system: y=-2x+2 and y=-x-2. We will start with the first one, we have to graph it. As we know 2 is y-int and -2 is a slope. Next step is to graph second equation. -2 is y-int and -1 is slope. Now we have two lines. We have to find place where two lines meet, this point will be the answer.
On the drawing we can see that two lines meet at (4,-6) point. It’s our answer.
