Answer: y-intercept
Explanation: A point is classified as (x, y) and in order for this ordered pair to be a y-intercept, we need to have the x-coordinate be 0.
Since the x-coordinate is 0, this is a y-intercept.
Answer: y = 0.5x + 35
Step-by-step explanation:
let x represent the number of minutes used by the customer in a month.
Let y represent the monthly cost for x minutes.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (435 - 215)/(800 - 360)
m = 220/440 = 0.5
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 360, y = 215 and m = 0.5 into y = mx + c. It becomes
215 = 0.5 × 360 + c
215 = 180 + c
c = 215 - 180
c = 35
The equation becomes
y = 0.5x + 35
Answer:
