To find the equation of the linear function, we first need to find the slope (M) and the y-intercept (B) using the given data points.
Let the number of cubic yards of soil ordered be x and the total cost be y.
Using the given data points:
(4, 220) and (7, 340)
Slope (M) = (340 - 220) / (7 - 4) = 120 / 3 = 40
y = 40x + B
Substitute one of the data points to solve for B:
220 = 40(4) + B
220 = 160 + B
B = 220 - 160
B = 60
Therefore, the equation of the linear function is:
y = 40x + 60
Last year Aleah ordered 4 yd.³ of soil and spent $220 this year she orders 7 yd.³ of soil and spends $340 right to the equation of the linear function that models the relationship between the number of cubic yards of soil ordered, and the total cost enter your answer and why equals MX plus B form
