Answer:
"The electrician charges an initial fee of $42", AND "The electrician charges $22 for every hour worked" is true.
Step-by-step explanation:
The equation is y=22x+42.
The formula is y=mx+b.
m is the slope, or is this case, the number of dollars for every "x", which is the number of hours worked. So you have to pay $22 for every hour the electrician works.
b is the y-intercept, or the amount it starts with, in this case, you have to pay a fee of $42 even when the electrician worked 0 hours. This is because $42 is the amount it starts with.
On a graph, the line will start at (0,42) because that is when you start paying. And then it will increase by 22 for each hour, so the next coordinate would be (1,64).
