Answer:
The answer is "40 nickels/standard coins"
Step-by-step explanation:
The ratio of 40 nickels/standard coins is constant, that is 1 roll with coins per 40 nickels, that's why the equation is y = 40 
All of our equations are in slope-intercept form. Slope-intercept form is y=mx+b. m stands for the slope, and b stands for the y-intercept. Our y-intercept is 3. Therefore, we can eliminate the equations that say the y-intercept isn’t b. Next, we can find the slope. We have the points (0, 3) and (3, 2). The formula for slope is y2-y1/x2-x1. 2-3 is -1, 3-0 is 3. Our slope is -1/3. After eliminating those without the y-intercept, we have A or D. We know that the slope is -1/3, so the answer must be D.
Solving the slope,
m = (y2 - y1)/(x2 - x1)
m = (1 - 5)/(3 - 6)
m = (-4)/(-3)
m = 4/3
The answer is c.
It should be the second one but I can’t really see it
