explanation:
4m-2=6
———
3
multiply 3 on both sides to cancel the 3 out
4m-2=18
add 2 from both sides to cancel the 2 out
4m=20
divide both sides by 4 to cancel out the 4
Answer:
m = 5
Step-by-step explanation:
4m - 2 / 3 = 6
4m - 2 / 3 * 3 = 4m - 2
6 * 3 = 18
4m - 2 = 18
4m - 2 + 2 = 4m
18 + 2 = 20
4m = 20
4m / 4 = m
20 / 4 5
m = 5

18. Elyse has a gift card that she can use to
rent movies online. The graph shows the amount of
money remaining on her gift card based on the number
of movies she rents.
a. Write an equation to represent the situation.
b. What is the y-intercept, and what does it mean in the
context of the situation?
c. What is the slope, and what does it mean in the context
of the situation?
Answers
Answer:
Step-by-step explanation:
The complete question in the attached figure
Let
x ----> the number of movies
y ----> the amount of money remaining on her gift card
we know that
The slope of the linear equation is equal to the unit rate
take two points from the graph
(0,18) and (2,12)
Find the slope
---> is negative because is a decreasing function
That means -----> Each movie she rents cost her $3, so her gift card balance will decrease $3 for every movie rented
The linear equation is equal to
For y=0
so
6 is the maximum number of movies that Elyse can rent on line
The solution is
a) The equation of line is y = -3x - 6
b) The y-intercept of the line is -6 which means when the number of movies x = 0 , the amount on gift y = -6
c) The slope of the line is -3 which means the rate of change of amount on gift is decreasing with number of movies x
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be A
The value of A = A ( 2 , 12 )
Let the second point be B = B ( 4 , 6 )
a)
Now , the slope of the line is given by the equation
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
On substituting the values in the equation , we get
Slope m = ( 6 - 12 ) / ( 4 - 2 )
Slope m = -6/2
Slope m = -3
Therefore , the slope is -3
The equation of line is given by the formula
y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 12 = -3 ( x - 2 )
On simplifying the equation , we get
y - 12 = -3x + 6
Adding 12 on both sides of the equation , we get
y = -3x - 6
So , the equation of line is y = -3x - 6
b)
The y intercept of the equation of line y = -3x - 6 is -6 , when x = 0
c)
The slope of the line y = -3x - 6 is m = -3 and the value is decreasing
Hence ,
a) The equation of line is y = -3x - 6
b) The y intercept of the equation of line y = -3x - 6 is -6
c) The slope of the line y = -3x - 6 is m = -3
