Answer:
Equation of line best fits the scatter plot is y = [tex]-\frac{30}{7} x + 108[/tex]
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] where ([tex]x_2,y_2[/tex]) and ([tex]x_1,y_1[/tex]) is the points on line
let, points be (4,96) and (18,36)
on calculating this m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = [tex]-\frac{30}{7}[/tex]
Therefore equation of line best fits the scatter plot is y = [tex]-\frac{30}{7} x + 108[/tex]
