Question

phone plan. The monthly cost c of marge's phone plan is given by c=40 + m, where m is the number of extra minutes she uses in that month. Name the slope and y-intercept in this situation, and explain what each represents

Answer 1

The slope of the phone plan is 1, representing the increase in cost per extra minute used. The y-intercept is 40, representing the fixed cost of the phone plan.

Step-by-step explanation:

The slope of the phone plan is given by the coefficient of the variable 'm' in the equation. In this case, the slope is 1, which means that for every additional minute used, the monthly cost increases by $1.

The y-intercept of the phone plan is given by the constant term in the equation, which is 40. This represents the fixed cost of the phone plan, regardless of the number of extra minutes used.

Answer 2

this equation takes the form y=mx+c.
however many minutes she uses, the base rate is 40.
y=mx+40.
c, 40 is the y intercept as it is when the number of miutes is 0.
there is no constant for m so we say it is 1. for every 1 minute used, the price goes up 1.
