Question

ACT MATH REVIEW PLEASE HELP: what is the slope of any parallel line to the line 7x+9y=6?

Answer 1

@Vocaloid

Answer 2

well, first calculate the slope, do you know how do to that?

Answer 3

y2-y1/x2-x1

Answer 4

uh, well, that would work if we were given two points, but we don't have that here, so we're going to use a different method

Answer 5

are you familiar with the equation y = mx + b?

Answer 6

yes

Answer 7

well, we're going to take our equation

7x + 9y = 6
and re-arrange it so it looks like y = mx + b

so let's start off with 7x + 9y = 6

subtract 7x from both sides, what do you get?

Answer 8

9y=-1x

Answer 9

uh, not quite

remember, you can't combine 7x and 6, so we leave it like this:

9y = 6 - 7x, with me so far?
