Slope intercept form of the line is y =
x|-9 -8 -7 -6
y|10 7 4 1
first take two points and FIND EQUATION of straight line given 2 points
let points be (-9,10) and (-8,7)

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (-9, 10) and (x2, y2) = (-8, 7).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%287-10%29%2F%28-8--9%29+=+-3.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or -3%2A-9+%2Bb+=+-17. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=10--3%2A-9+=+-17.

y=(-3)x + (-17)

Your graph:





so,
y=+-3x+-17 is slope-intercept form
