Answer:
-1.3
Step-by-step explanation:
The graph shows the straight line passing through the points (3,-1) and (-3,7).
The slope of the line passing through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is
[tex]\dfrac{y_2-y_1}{x_2-x_1}[/tex]
In your case, the slope is
[tex]\dfrac{7-(-1)}{-3-3}\\ \\=\dfrac{7+1}{-6}\\ \\=-\dfrac{8}{6}\\ \\=-\dfrac{4}{3}\\ \\\approx -1.3[/tex]
The rate of change is -1.3
