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!
