Answer:
The expression is equal to
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to
The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute
For x=h hours
substitute
Answer:
y = x - 5
Step-by-step explanation:
The equation of the line parallel to the line is
.
That is, equations of parallel lines differ only by constant.
The given equation is
This is written as
Therefore, the equation of the line parallel to this line is given by
The value of c is determined using the point given.
Substituting the point (3,-2) we get:
Therefore, the equation of the line becomes y = x - 5.
