## anonymous one year ago Can someone tell me what I'm doing wrong here? I like.. just did everything I had to do.. I don't see how 1/2 is the answer http://prntscr.com/7eemx3

Solve for y to get $\Large 2x - 4y = 10$ $\Large 2x - 4y{\color{red}{-2x}} = 10{\color{red}{-2x}}$ $\Large -4y = -2x+10$ $\Large \frac{-4y}{{\color{red}{-4}}} = \frac{-2x+10}{{\color{red}{-4}}}$ $\Large \frac{\cancel{-4}y}{\cancel{-4}} = \frac{-2x}{-4}+\frac{10}{-4}$ $\Large y = \frac{1}{2}x - \frac{5}{2}$ The last equation is in the form y = mx+b where the slope is m = 1/2

Wow.. Thank you. :) I was totally off track xD Thank you for explaining. c:

Your method would work only if you had 2 points. But you had the right idea somewhat

4. jim_thompson5910

Also, the two points are (5,0) and (0,-2.5) notice how the 2.5 is negative

5. jim_thompson5910

and the slope formula is $\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ the y difference is up top. So you had that mixed up as well

Oh, I didn't know that x) Thanks again c:

no problem
