Final answer:
The equation for CE is y=4/5(x+1).
Step-by-step explanation:
The equation for CE is:
c.) y=4/5(x+1)
This equation is in the form y = mx + b, which is the standard form of a linear equation. In this equation, m represents the slope (4/5) and b represents the y-intercept (1). So, the equation y = 4/5(x+1) represents a linear relationship between x and y, where the y-intercept is at (0, 1) and the slope is 4/5.
