Answer:
y = 90x + 50
Step-by-step explanation:
In this situation, let's define the variable and the constant.
The variable is what changes, so in this case the wage ($90) changes with how many hours the electrician is hired for.
The constant is the number that stays the same, in this case it would be the $50 traveling fee because it remains the same every time.
The equation should be written in this form:
y = mx + b
m = slope (variable)
b = y-intercept (constant)
Therefore, you can write the equation like this:
y = 90x + 50
