Two years after it’s purchase, if manuel’s gift card is unused, the automatic decrease on the gift card balance is given by the equation b = 50 - 5m, where m is the number of months beyond two years.

is this model of the siu action linear? if it is, what are the slope and y-intercept?

a. linear: slope = -10, y-intercept = 5
b. linear: slope = -50, y-intercept = 5
c. linear: slope = -5, y-intercept = 50
d. not linear

Option C. linear: slope = -5, y-intercept = 50

Step-by-step explanation:

Let

b ----> is the automatic decrease on the gift card balance

m ---->  is the number of months beyond two years

we know that

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-intercept

In this problem the linear equation that represent this situation is

---> equation of the line into slope intercept form

so

The slope is -5

The y-intercept is 50

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.
