The table shows the cost of renting ski equipment at a ski lodge. Write a linear function f for the sequence. Then graph the fun

Bingel [31]

Answer:

y=5x+7

or

f(x)=5x+7

Step-by-step explanation:

Slope (m) = 5

Y-intercept (b) = 7

Using the equation y=mx+b, you can find m and b to make y=5x+7.

Steps:

(1, 12) (2, 17) formula: y2-y1 / x2-x1 = m

17-12= 5

2-1 = 1

5/1=5

m=5

12=5(1)+b

12=5+b

7=b

17=5(2)+b

17=10+b

7=b

Answer: y=5x+7

or

f(x)=5x+7

Express it in slope-intercept form.

Hey there! :)

Answer:

y = 1/4x - 3.

Step-by-step explanation:

Use the slope-formula to find the slope of the line:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

Plug in two points from the line. Use the points (-4, -4) and (0, 3):

$m = \frac{-3 - (-4)}{0 - (-4)}$

Simplify:

m = 1/4.

Slope-intercept form is y = mx + b.

Find the 'b' value by finding the y-value at which the graph intersects the y-axis. This is at y = -3. Therefore, the equation is:

y = 1/4x - 3.
