18 points plus brainliest for correct answer find the equation of the line perpendicular to y=−2 that passes through the point (4, −2).

The line y = -2 is a horizontal line through -2 on the y axis.

Anything perpendicular to this horizontal line will be a vertical line. All vertical lines are of the form x = k where k is some fixed value.

In this case, the answer is x = 4 because want the vertical line to go through (4,-2). In other words, we want all points on the vertical line to have x coordinate of 4. 

Side Note: the slope of y = -2 is 0 while the slope of x = 4 is undefined. 

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
