Answer:
——
y=3x-17
——
Step-by-step explanation:
y=mx+b is the formula
m=slope, b=y-intercept.
Slope is given, 3
So y=3x+b
A point is also given, (3,-8) x=3,y=-8
-8=3(3) + b
-8=9+b
-17=b
So the equation is :
y=3x-17

Answer:
3 Hours
Step-by-step explanation:
Plumber A.
Initial fee: $45
Per Hour: $60
Plumber B.
Full rate: $225
To determine the number of hours it will take for both plumbers to charge the same amount you have to start with $45.
Then add 60$ every hour.
$45 + $60 = $105
$105 + $60 = $165
$165 + $60 = $225
Therefore, it takes 3 hours for them to charge the same rate.
