Question

Equation in slope intercept form of the line that passes through the given points of (2,-5) and (-8,3)

Answer 1

First find the slope: Y2-Y1/X2-X1 =-4/5 Then plug in 1 y coordinate and x coordinate to the equation: Y=mx+b Y=-4/5x +b Y=-4/5x-17/5  

Answer 2

Slope =  (3 - (-5)) /  (-8-2) =  8/-10 = -4/5

y = -4/5x + b    where b = slope intercept

when x = 2 y = -5 so:-

-5 = -4/5 * (2) + b

b =  -5 + 8/5 =  

Equation is  y = -4/5 x - 17/5     answer
