Y=mx+b
So the b, or y intercept, would be when x is 0. So the y intercept is 7.
Then to find the slope put it in the formula y2-y1/x2-x1 or rise/run. I’ll choose the first and second point. So (-1,5) and (0,7)
7-5/0-(-1)
And two negatives make a positive
So it is 2/+1 making the slope a positive 2.
So y=mx+b
y=2x+7
