Question

Write the equation of the line that goes through the

point (0,-3) and is perpendicular to the
line y=-(2/5)x+6.

Answer 1

y = 5/2x -3

Explanation:

Perpendicular lines have slopes that are negative reciprocals of one another

so slope is 5/2

Using (0,-3) => y = 5/2x + b

-3 = 5/2(0) + b

b = -3

y = 5/2x -3
