Answer:
[tex]\frac{6}{8}[/tex] (Proper Fraction)
Step-by-step explanation:
Pick any two points from the graph and trace points to the y-axis and x-axis.
slope of a graph m= y₂-y₁/x₂-x₁
From graph, points picked on the y-axis are 90 and 30, now trace this points to the x-axis, 90 on the y-axis is 90 on the x-axis and 30 on the y-axis is 10 on the x-axis.
Therefore,
y₂= 90
y₁= 30
x₂= 90
x₁= 10
slope of a graph m= y₂-y₁/x₂-x₁
Slope m= [tex]\frac{90-30}{90-10}[/tex]
m=[tex]\frac{60}{80}[/tex]
m=[tex]\frac{6}{8}[/tex]
