Question

Find the slope of the line passing through (-3,-4) (3,-2)

Answer 1

Slope is given by:

\[\large Slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 2

\[(x_1, y_1) = (-3, -4)\]

\[(x_2, y_2) = (3, -2)\]

Plug in these values and tell me what did you get as Slope...

Answer 3

Ok So I plotted these on my graphing paper and I get a slope of 3?

Answer 4

How did you get Slope = 3 ??

Answer 5

\[\large Slope = \frac{-2 -(-4)}{3 - (-3)} \implies \frac{-2 + 4}{3 + 3} = ??\]

Answer 6

I am also having trouble with 4x + 8y = 7 3x + 4y = 6 I am getting (5/3, 2/8)

Answer 7

Do you want to find the slope for these ??

Answer 8

No I just had to solve

Answer 9

Just multiply first equation by 3 and second equation by 4 and tell me what do you get..

Answer 10

I just re did it 4x+8y=7
3x+4y=6

-6x-8y=-12
4x+8y=7
-2x=-5
x=5/2

15/2+4y=12/2
4y=-3/2
y=-3/8
