Question

1. find the slope and y - intercept for the graph of the equation that represents the situation. at phones - r - us, xavier is paid $15 for every cell phone plan one of his customers purchases. the equation d = 15c can be used to represent this situation where d is xaviers total pay and c is the number of cell phone plans he sells. number of cell phones plans sold, c 0 1 2 3 4 total pay, d 0 15 30 45 60 a. the slope is 0 and the y - intercept is 15. b. the slope is 15 and the y - intercept is 0. c. the slope is undefined and the y - intercept is 15. d. the slope is 15 and the y - intercept is 15.

Explanation:

Step1: Recall slope - intercept form

The slope - intercept form of a linear equation is $y = mx + b$, where $m$ is the slope and $b$ is the y - intercept. Given the equation $d = 15c$, we can rewrite it as $y = 15x+0$ (where $d$ is like $y$ and $c$ is like $x$).

Step2: Identify slope and y - intercept

For the equation $y = 15x + 0$, the coefficient of $x$ is the slope. So, $m = 15$, and the constant term is the y - intercept. So, $b = 0$.

Answer:

B. The slope is 15 and the y - intercept is 0.
