Answer:
Step-by-step explanation:
Let x represent the number of video games that Kevin rents.
Let y represent the total amount that he paid for x video games rental.
The slope intercept form of an equation is expressed as
y = mx + c
Where
m = slope
c = intercept
When Kevin rented 2 games, he had spent a total of $25 of his money. When Kevin rented 2 more video games (4 total), he then had spent $30 total of his money at this store all together. Therefore,
Slope, m = (30 - 25)/(4 - 2) = 5/2 = 2.5
To determine the intercept, c, we will substitute m = 2.5, x = 4 and y = 30 into y = mx + c. It becomes
30 = 2.5 × 4 + c
30 = 10 + c
c = 30 - 10 = 20
The Slope-Intercept Form to model how much Kevin pays per x video game rentals with his store membership becomes
y = 2.5x + 20
The cost per video game rental is $2.5
The membership fee is $20
The graph of a non member's yearly cost is steeper, and also has a lower y-intercept. And the graph of a member's yearly cost starts higher, but is less steep.

Step-by-step explanation:
The coordinate plane is also called a Cartesian Plane. Function. A function is a relationship where there is only one output for every input. In other words, for every value of x, there is only one value for y.

The question in English is
The age of 4 members of a family adds up to 70. Mom is 6 times bigger than her son and 10 times bigger than her daughter. Dad is 2 years older than Mom. How old are each of the family members? Write the result in ascending order and separated by spaces
Let
x----> Mon's age
y----> Son's age
z----> Daughter's age
w---> Dad's age
we know that
x+y+z+w=70 -----> equation A
x=6y ----> y=x/6 -----> equation B
x=10z ----> z=x/10 -----> equation C
w=2+x -----> equation D
substitute equation B, C and D in equation A and solve for x
x+(x/6)+(x/10)+(2+x)=70
Multiply by 60 both sides
60x+10x+6x+120+60x=4,200
136x=4,200-120
x=4,080/136
x=30 years
Find the value of y
y=x/6 -----> y=30/6=5 years
Find the value of z
z=x/10 ----> z=30/10=3 years
Find the value of w
w=2+x ----> w=2+30=32 years
Write the result in ascending order and separated by spaces
3 5 30 32
so
Daughter Son Mon Dad
