Write the equation in slope-intercept form of the line passing through (2,7) and (-5,2).
sasho [114]

Hello!

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

Rise/run.

m=\frac{rise}{run}

x^1,y^1=(2,7)

x^2,y^2=(-5,2)

\frac{2-7=-5}{(-5)-2=-7}= \frac{-5}{-7}

\frac{-5}{-7}=0.714

<u><em>Y-intercept is -7</em></u>

<u><em>But the slope is -5.</em></u>

<u><em>Answer: → 0.714</em></u>

Hope this helps!
