What equation is used to solve for an interior angle of a triangle?
A.) a+b+c= 360
B.) a + b = 90
C.) a+b+c=180
D.) a + b = 180

c) a+b+c=180

Step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
