Question

What is the slope of the line through (-5, -10) and (-1, 5)?

Answer 1

y = 5/4 + -35

Explanation:

Slope m = (y2-y1)/(x2-x1)

m = (-5 - -10)/(-1 - -5)

m = 5/4

Slope-intercept: y = mx + b

using (-5, -10)

-10 = 5/4(-5) + b

-10 = -25/4 + b

b = -10 - 25 = -35

b = -25 - 25 = 0

then y = 5/4 + -35
