Answer: Slope of the line = 0.75.
Step-by-step explanation:
Since we have given that
Number of tests = 27
Number of weeks = 36
According to question,
Number of tests is on the y-axis and the time in weeks is on the x-axis.
So, the coordinates are the (0,27) and (36,0)
As we know the formula for "Slope of line":
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{27-0}{36-0}\\\\m=\frac{27}{36}\\\\m=\frac{3}{4}\\\\m=0.75[/tex]
Hence, Slope of the line = 0.75.
