first find the slope:



slope = -2
Then use y=mx+b and substitute one set of points into the equation:
-8=-2(9)+b
-8=-18+b
b=10
so the equation is y=-2x+10

Solved by pluggable solver: FIND EQUATION of straight line given 2 points
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, -8) and (x2, y2) = (7, -4).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-2)x + (10)
