Question

Choose the equation of the line passing through the point (4, -2) and perpendicular to
y = 1/3x - 7.



y = -3x - 14

y = 3x - 10

y = -3x + 10

y = 3x + 14

Answer 1

To start, the slope of the line will be the negative reciprocal of the given line.

Answer 2

Then, it will be in the form y = mx + b. Stick in the m from the previous step, then stick in the y and x of the given point, and you will have an equation in one variable, b. Solve for b and then you're done.
