Question

Fine the slope of the line through each pair of points . (-8,-20),(5,2)

Answer 1

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-8, -20) and (5, 2). Substitute:

$m=\dfrac{2-(-20)}{5-(-8)}=\dfrac{22}{13}$

Answer: The slope is $\dfrac{22}{13}$

Answer 2

Hello username!

Explanation:

Slope-intercept form: → $y=mx+b$

m: represents the slope and is constant.

b: represents the y-intercept.

rise/run

$m=\frac{rise}{run}$

$m=\frac{y^2-y^1}{x^2-x^1}$

$x^1,y^1=(-8,-20)$

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

$\frac{2-(-20)=2+20=22}{5-(-8)=5+8=13}=\frac{22}{13}$

But the slope is 22/13.

Answer: $\boxed{=22/13}$

Hope this helps!

Thank you :)
