Question

Write an equation of the line passing through the point (9, -3) that is perpendicular to the line y = -3x + 458,983.

If your b value is negative, enter it into the box negative.

Enter your slope as a fraction. Do not use decimals for your slope.

Answer 1

slope = 1/3, the inverse negative of the given line's x coefficient

y= (1/3)x + b, where b = the y intercept.

plug the point in, y=-3, x= 9

-3 = (1/3)(9) + b, solve for b

b = -6

the line equation is y= (1/3)x - 6
