Hi
*Note: there are 2 steps to finding the y = mx + b equation for this line
.
find slope:
m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29
.
(-10, -3) (-1, 1)
m+=+%281-%28-3%29%29%2F%28-1+-+%28-10%29%29+=+%284%2F9%29
.
finding b
y = (4/9)x + b
.
Using Pt(-1,1)
1 = (-4/9) + b
.
13/9 = b
.
y = (4/9)x + (13/9)
