Answer:
A. The slope is 4.
B. The y-intercept is 8.
C. The equation is y = 4x + 8
Explanation:
We know that there is a flat $8 cost in addition to $4 per ride. We can express this by using:
y = 8 + 4x.
y is the total cost
x is the number of rides
The question wants the equation in slope-intercept form.
Slope-intercept form of a line: y = mx + b
m = slope
b = y-intercept
y = 8 + 4x ➵ y = 4x + 8
Now that we have the slope-intercept form of the line, we can answer the problems.
A. The slope is 4.
B. The y-intercept is 8.
C. The equation is y = 4x + 8
