Answer:
Slope = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Slope of a straight line passing two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Line is passing through two points (20, 5) and (80, 20),
Therefore, slope of the line will be,
m = [tex]\frac{20-5}{80-20}[/tex]
m = [tex]\frac{1}{4}[/tex]
The slope is [tex]\frac{1}{4}[/tex].
