Question

Write the equation of a line that is perpendicular to y = 1/2x - 7 with a y-intercept of 15.

What is the perpendicular slope?
What is the new equation?

Answer 1

m = -2

y = -2x + 15

Explanation:

so it's asking for the perpendicular slope so perpendicular means negative reciprocal so the negative reciprocal of 1/2 is -2

and since the question has already provided the y intercept, just write out the new equation in slope intercept form so y = -2x + 15. hope this helps
