In order to find this don't I have to find the slope of the lines again? @iGreen

anonymous · Answer

can i get help with my question please ?

perl · Answer

each line, you have to determine the slope

What's the slope of y = 2x - 2?

anonymous · Answer

m = 2

igreen · Answer

Yep.

igreen · Answer

Let's rearrange 6x - 7y = 21 into slope-intercept form.

First, subtract 6x to both sides:

-7y = -6x + 21

Divide -7 to both sides:

y = 6/7x - 3

So what's the slope of this one?

anonymous · Answer

m = 6/7

igreen · Answer

Yep.

anonymous · Answer

I just find the slope of each answer choice and whichever answer has the higher value slope will be my answer?

igreen · Answer

Yep.

igreen · Answer

Rate of Change is the same thing as Slope.

Thanks(:

igreen · Answer

For #3, we can take two points and plug them into the slope equation.

Let's take (2, 7) and (3, 13).

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{13-7}{3-2}$

Can you finish that? @iRespect

igreen · Answer

@H2adeelo Don't give answers, plus your answer is wrong..

anonymous · Answer

M = 6

anonymous · Answer

I think C is correct

igreen · Answer

Yep, that's right..it's 6..and C is your answer..the slope of D is 3..

igreen · Answer

#1 = 6/7
#2 = 2
#3 = 6
#4 = 3
