A)what year would be represented by x=4?

B)What x-value represents the year 20018?

C)what is the slope (or rate of change) of this equation?

D)what is the y-intercept?

To find the answers to these questions about the linear equation y = 0.15x + 0.79, we will follow the given equation and perform some basic calculations.

A) To find the year represented by x = 4, substitute x = 4 into the equation and solve for y:
y = 0.15(4) + 0.79
y = 0.6 + 0.79
y = 1.39
Therefore, x = 4 represents the year 1.39.

B) To find the x-value representing the year 20018, we need to solve the equation for x:
20018 = 0.15x + 0.79
20018 - 0.79 = 0.15x
19202 = 0.15x
x = 19202 / 0.15
x ≈ 128,013.33
Therefore, the x-value representing the year 20018 is approximately 128,013.33.

C) The slope (or rate of change) of the equation can be determined by looking at the coefficient of x in the equation. In this case, the coefficient of x is 0.15. The slope can be interpreted as the amount y changes for a unit increase in x. So, the slope of this equation is 0.15.

D) The y-intercept represents the point where the line intersects the y-axis. In the equation y = 0.15x + 0.79, the y-intercept is given by the constant term, which is 0.79. Therefore, the y-intercept is 0.79.
