Question

What is the equation of a line that passes through the point (3, -1) and is perpendicular to a line with a slope of 3/4

Answer 1

What is the equation of a line that passes through the point (0, -3) and is perpendicular to a line with a slope of 4?

Answer 2

One question at a time. You want to put into the equation of a line form, which is y = mx+b.

You are given x and y (3, -1) and slope (m) = 3/4.

Just substitute these values into the equation to solve for b.

Do this now. Once you solve for b, you can put everything together.

Answer 3

sorry that was the wrong question

Answer 4

Doesn't matter, it's the same process.

Answer 5

@iambatman, the slope of the equation of the line is different from the slope of the perpendicular line.

Answer 6

-3=4(-1)+b

Answer 7

Right, just take the negative reciprocal for the slope.

Answer 8

y=1/4+3
