Respuesta :
The slope is (135 - 15)/(12 - 0) = 120/12 = 10
The slope represents the average monthly cost of gym membership.
The y-intercept is the value of y when x = 0, y-intercept = 15.
The y-intercept represent the the initial membership cost.
The slope represents the average monthly cost of gym membership.
The y-intercept is the value of y when x = 0, y-intercept = 15.
The y-intercept represent the the initial membership cost.
The correct answers are:
The slope is 10.
The slope represents the cost of gym membership per month.
The y-intercept is 15.
The y-intercept represents the cost of gym membership on the first day of attendance.
Explanation:
The points we are given are (0, 15) and (12, 135).
We will find the slope first, using the formula:
[tex] m=\frac{y_2-y_1}{x_2-x_1} [/tex]
Plugging in our values from our ordered pairs, we have:
[tex] m=\frac{135-15}{12-0}=\frac{120}{12}=10 [/tex]
The slope is 10.
The graph shows us the cost along the y-axis and the number of months along the x-axis. This means it costs $10 for every 1 month of gym membership.
The y-intercept is the point where the data crosses the y-axis. Our graph goes through (0, 15); this point lies on the y-axis, so this is our y-intercept.
The y-intercept shows us the cost at 0 months; it costs $15 to begin a gym membership before the 1st month.
