Answer:
26mph
Step-by-step explanation:
18 miles at 36mph will take 30 minutes and 26 × 7 is 3 h 30 min
Y=1 we can check this by looking at the slope of the line: m=

so m=0. By looking at the graph we know our y-int is 1. By plugging in this information into the equation of a line we get the following: y=0x+1. That is y=1
We have the equation:

Given the slope-intercept formula for the equation of the line, we have the following:

Now, since we have that t is the number of hours the electrician spends working, the slope of the function represents the hourly rate charged.
The inverse of this would be
