Answer: B. 2/5 *The answer must have a fraction.

Explanation:

Slope-intercept form: → [tex]y=mx+b[/tex]

m: represents the slope and is constant.

b: represents the y-intercept.

Used rise/run.

[tex]\frac{rise}{run}[/tex]

[tex]x^1,y^1=(-2,2)[/tex]

[tex]x^2,y^2=(3,4)[/tex]

You had to find the slope by using formula.

[tex]Slope=\frac{y^2-y^1}{x^2-x^1}[/tex]

[tex]\frac{4-2}{3-(-2)}[/tex]

subtract by the numbers and add the numbers too.

[tex]\frac{4-2=2}{3-(-2)=3+2=5}[/tex]

[tex]=\frac{2}{5}[/tex]

Hope this helps!
