Which of the following equations represents a line that is perpendicular to
y = -2x + 4 and passes through the point, (4,2)?

y = 1/2x

Step-by-step explanation:

y = 1/2x or y = 1/2x + 0

Unfortunately, I can't see your image because my school blocked the image. :(

Step-by-step explanation:

First, you should know that when a line is perpendicular, it has the opposite reciprocal slope. So, we know the slope is 1/2. Next, we need to find the y-intercept, so we will plug in the point to the equation. It should look like this: 2 = 1/2(4) + b. Multiply 1/2 by 4 to get 2. You now have this: 2=2+b. You want to get the b by itself, so subtract 2 from both sides to get 0 = b. So, the y intercept is 0. However, because it is a 0, you can just write your answer as y=1/2x. Unfortunately, I can't see your image because my school blocked the image. :(

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
