Answer is 18 hours worked
Step by step:
Equation y = mx + b
Our total income (y) is $1305
Our rate (m) is $35
Our y intercept (b) is $75 * 9 home visits
Our unknown hours worked is X
1305 = 35x + (75*9)
1305 = 35x + 675
Subtract 675 from both sides to isolate the variable
1305 - 675 = 35x + 675 - 675
$630 = 35x
Divide both sides by 35 to solve for x
630/35 = 35/35 x
18 = x hours worked
Check your work
Substitute your x value into the equation
1305 = 35x + (75*9)
1305 = 35*18 + (75*9)
1305 = 630 + 675
1305 = 1305
Problem solved!
