Write an equation of the line that passes through (-3, 4) and is perpendicular and parallel to the line y = 2/3x + 2

2 lines?

Gradient of line * gradient of perpendicular line = -1

Use formula for gradient + point = line

This is high school algebra shit get the fuck out

First we solve for the slope of each line. A Parallel line will have the same slope and a perpendicular line will have a negative inverse slope (so 7/3 becomes -3/7).

The slopes of our lines are
2/3 (parallel)
and -3/2 (perpendicular)

Now we need to find a formula for lines that have these slope and pass through a particular point. We have a slope, and a point, for each line. So we can now plug them into the point slope formula. I don't remember that formula and don't feel like googling it though so you're on your own now. If you can't finish it from here you need to hire a tutor because you're missing fundamental understandings that you should have by now.

don't you think if you stopped helping everyone with homework people would eventually stop coming here just for that? Like half of the threads here are just people who are too lazy to do their homework.

You must be retarded, any chemistry paper (inorg or o) has C's written in.

very often the majority of carbon atoms are not specified by "C" in (this isn't 1950...)

to follow up on this (>>5290955, b/c I accidentally hit send before I was finished posting, derp), for example look at these abstracts from the current issue of Org. Lett.
