Question

For the graph y = 12 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences.

Answer 1

The line y = 12, is a horizontal line parallel to the x-axis and passing through all points on the plane with a y - coordinate of 12.

Since it is parallel to the x-axis it's slope is zero.

graph{(y-0.001x-12)=0 [-40, 40, -20, 20]}
