Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug the given points (80,20) and (120,30) into the equation
[tex]\frac{y_2-y_1}{x_2-x_1}\\= \frac{30-20}{120-80}\\= \frac{10}{40}\\= \frac{1}{4}[/tex]
Therefore, the slope of the line that passes through these points is [tex]\frac{1}{4}[/tex].
I hope this helps!
