Answer:
Pls don't get mad if I get this wrong but y=0.25x-0.5
Explanation:
We can use solve this problem with cancelling the b's in the equations.
We can find m by using the (y2-y1)/(x2-x1) formula.
We end up with the two equations:
-1 = -2m+b
1 = 6m+b
Here, we can cancel out the (b)'s and find the value of m.
m=0.25
After I did this, I plugged the m into both equations to find b.
-1 - (-2*0.25)=b
I got -1/2 for b.
This is how I got y=0.25x-0.5b
