Answer:
I dine at home
Step-by-step explanation:
Answer:
The formula y = mx + b sometimes appears with
different symbols.
For example, instead of x, we could use the
letter C. Instead of y, we could use the letter F.
Then the equation becomes
F = mC + b.
All temperature scales are related by linear
equations. For example, the temperature in
degrees Fahrenheit is a linear function of degrees Celsius.
Water freezes at: 0°C, 32°F
Water Boils at: 100°C, 212°F

Answer:
$4.25 x 60 = $ 255.00
Step-by-step explanation:
Answer:
Pat a) The unit rate of graph at left is 
Part b) The unit rate of graph at right is 
see the attached figure
Step-by-step explanation:
we know that
The unit rate of a linear equation is the same that the slope of the linear equation
step 1
Find the slope of the graph at left
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k

we have the point (1,25)
substitute the values in the formula

step 2
Find the slope of the graph at right
we have the points (2,80) and (3,120)
This graph represent a proportional relationship (because the line passes through the origin)
The slope is equal to the constant of proportionality k

Is necessary only one point to determine the constant of proportionality
take the point (2,80)
substitute the values

<u>Verify</u>
The formula to calculate the slope between two points is equal to

we have the points (2,80) and (3,120)
substitute the values
