Answer:
y= -2x +2
Step-by-step explanation:
<u>Slope-intercept form:</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -2, m= -2.
Substitute m= -2 into the equation:
y= -2x +c
Given that the y-intercept is 2, c= 2.
Substitute c=2 into the equation:
y= -2x +2

-6 = -3x -12
6 = -3x
x = -2
y = -3(-2) -12
y = 6 -12
y = -6
(-2,-6)
The answer is the third choice: -1
