The slope can be said to be the cahnge in the values of y divide by the change in the values of x.
To find the slope, apply the slope formula below:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
From the given graph, take the points on the line:
(x1, y1) ==> (10, 80)
(x2, y2) ==> (30, 90)
Input values into the formula and solve for m.
Thus, we have:
[tex]\begin{gathered} m=\frac{90-80}{30-10} \\ \\ m=\frac{10}{20} \\ \\ m=\frac{1}{2} \end{gathered}[/tex]
Therefore, the slope is ½
ANSWER:
[tex]\frac{1}{2}[/tex]
