Question

Write the equation of the line that passes through the points (2,-6)and (-2,-4).Write the equation in slope intercept form

Answer 1

First find the slope
Slope formula: (y2-y1)/(x2-x1)
(-4-(-6))/(-2-2) = 2/-4 = -1/2
Slope intercept formula: y = mx + b
Y = -1/2x + b (solve for b)
Plug in any point
-6 = -1/2(2) + b
-6 = -1 + b, b = -5

Solution: y = -1/2x - 5
