1. Find the measure of angle b (image attached below)

2. Find the measure of angle b (image attached below)

1. 37° 2. 140

Step-by-step explanation:

They are supplementary angles, so the angle measures equal a straight line, or 180 degrees. 180 - 143 = 37

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. : )
