Question

Using Slope-Intercept Form
Use slope formula,m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction, to find the slope of a line that passes through the points (–3, 8) and (4, –6).

m =
Use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line.

b =
What is the new equation written in slope-intercept form, y = mx + b?

Answer 1

m = (-6 - 8) / (4 - (-3)) = -14 / 7 = -2

b: use y = mx + b with (−3, 8): 8 = (-2)(-3) + b = 6 + b ⇒ b = 2

Equation: y = -2x + 2
