I really need help. My teacher said that I could use any number.

katen-ka-za [31]

The keyword is Rise over run
So the 2nd y value minus the first y value and divide it by the 2nd x value minus
(y2-y1)/(x2-x1)
(10-7)/5-3)
the first x value and you should get 3/2
*dont worry the if the number is under and not above it’s not a saying to do to the power of but it’s just saying the order in which to put the x and y values.

Answer:

$m = -\frac{194}{3}$

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by $\frac{4}{3}$

$256=-\frac{8}{3} - 4m$

add $-\frac{8}{3}$ to both sides

$258\frac{2}{3}=-4m$

I would get rid of the fraction so I'd multiply both sides by $\frac{3}{1}$

$\frac{776}{3}*3 = 4m*3$

$776=-12m$

divide both sides by -12m

$m = -\frac{776}{12}$

which can be simplified to

$m = -\frac{194}{3}$

ALL UNLESS THAT $\frac{4}{3}$ IS A POWER
