Question

The ordered pairs for two points are listed in the table. What is the equation, in slope-intercept form, of the line that contains these points?
x l y
-1 l 3
1 l -7

A. y = -5x + 2
B. y = -5x - 2
C. y = 2x + 5
D. y = 2x - 5

Answer 1

Answer:

y = 5x - 2

Step-by-step explanation:

(-1,3) (1,-7)

Slope (m) = (-7-3)/(1+1) = -10/2 = -5

(-1,3)

y-y = m(x-x) = y-3 = -5(x - -1) = y-3= -5(x+1) =

y-3 = 5x-5

y = 5x - 5 + 3

y = 5x - 2
