Question

Write the equation of the line that passes through the given point and is perpendicular to the given line. Your answer should be written in slope-intercept form.
P(3, −4), x = − 7/8y + 3

Answer 1

your given line has slope -7/8
So a perpendicular line has slope 8/7
Now you have a point and a slope, so the equation is

y+4 = 8/7 (x-3)
now rearrange to y=mx+b form

Answer 2

how do i do that im lost on this stuff

Answer 3

really?
y+4 = 8/7 (x-3)
y+4 = 8/7 x - 24/7
y = 8/7 x - 24/7 - 4
y = 8/7 x - 52/7

You have only learned a few rules for this stuff, so you know that whatever they ask you to do will look a lot like examples they have already given you. Like anything else you are good at, it just takes practice.

Answer 4

Thank you im online so i have to learn reading and practice and go to tutor but they take forever to get back to students
