Jack works after school. Each day he is paid a set amount, plus an hourly wage. Look at the table. Choose the linear function f
daser333 [38]

Answer:

A. f(x) = 10x + 8

Step-by-step explanation:

The equation in slope-intercept form, f(x) = mx + b, can be created to be used in finding Jack's pay. We need to find the slope (m) and the y-intercept (b) of the linear function.

Using two points (1, 18), and (1.5, 23), find the slope (m):

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10

Find b, by substituting x = 1, f(x) = 18, and m = 10 into f(x) = mx + b.

18 = (10)(1) + b

18 = 10 + b

Subtract 10 from each side

18 - 10 = b

8 = b

b = 8

Substitute m = 10 and b = 8 into f(x) = mx + b.

✅Thus, the linear function that can be used to find Jack's pay would be:

f(x) = 10x + 8
