Question

What is the slope-intercept equation of this line?

(0,4)
(2,-2)
A. y=-3x + 4
B. y = 4x - 3
C. y = 3x + 4
D. y = - 1/3 x+4

Answer 1

A

Explanation:

use both points to find the slope using the equation

y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3

then the y int can be any y point, so either -2 or 4. in this case they used 4.
