Question

elenas pay (graph with x-axis from 0 to 4, y-axis from 0 to 40, line starting at (0,10) and going up. options: a. $25, b. $50, c. $20)

Explanation:

Step1: Identify the equation of the line

The graph is a linear graph with a y - intercept of 10 (when x = 0, y = 10) and we can find the slope. Let's take two points, (0, 10) and (2, 40). The slope $m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{40 - 10}{2 - 0}=\frac{30}{2}=15$. So the equation of the line is $y = 15x+10$.

Step2: Assume we want to find the pay for x = 1 (if the question is about pay per hour or something similar)

Substitute x = 1 into the equation $y=15\times1 + 10=25$. So the pay is $25, which corresponds to option A.

Answer:

A. $25
