Answer 1

@ali1029 @AllTheLonelyKillers @littlelotte @ganeshie8 help and sorry for tagging!

Answer 2

sorry i dont know how to do that :(

Answer 3

hmm, what would be the slope of that line?

Answer 4

idk im confused

Answer 5

\(\bf slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}\)

Answer 6

\(\bf slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}\\
\textit{look at your 2 points in the graph } (-4,-1)\qquad \left(\frac{1}{2}, 3\right)\\\quad \\
\cfrac{y_2-y_1}{x_2-x_1} \implies \cfrac{(3)-(-1)}{\left(\frac{1}{2}\right)-(-4)}\)

Answer 7

keep in mind that \(\bf 4 \implies \cfrac{8}{2}\\\quad \\
\cfrac{(3)-(-1)}{\left(\frac{1}{2}\right)-(-4)} \implies \cfrac{(3)-(-1)}{\left(\frac{1}{2}\right)-\left(-\frac{8}{2}\right)}\)

Answer 8

ok
