slope=(y2-y1)/(x2-x1)=(-9-7)/(3+1)=-16/4=-4
by Level 6 User (24.5k points)

First find the slope which we get by dividing the difference of the y coords of the given points by the difference of the x coords: (-9-7)/(3-(-1))=-16/4=-4.

Then we take either point to build the equation of the line:

Using point (-1,7) we get:

y-7=-4(x+1), y-7=-4x-4, y=-4x+3 in slope-intercept form. The other point automatically fits this equation: -9=-4×3+3.

Answer: y=-4x+3.
