Answer:
C. 40
Step-by-step explanation:
20 + 4x = 180
subtract 20 from both sides
4x = 160
Divide both sides by
x = 40
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:

0.4kg per week. so 0.4kg x 6 weeks is 2.4kgs
Answer:
Equation point-slope model is: y-16 = 4 (x-7)
Slope =4
x-intercept=(7,2)
y-intercept=(16,-4)
