The slope of a line is given by the equation
y2 is -4. y1 is 5
x2 is 4. x1 is 1
-4 -5 / 4-1 = -9/3 = -3
The slope is -3. Now we need to find the y-intercept
y= mx +b
5= -3(1) +b
5= -3 +b
b= 8
Our equation for the line: y= -3x +8
Regular time:
wage: $18/hour * 40 hours = $720
Over time:
1.5 * $18/hour * number of hours over 40
number of hours over 40 = x - 40
wage = 1.5 * 18 * (x - 40) = 27(x - 40) for x ≥ 40
Total wage:
wage = $ 720 + 27 ( x - 40) ; x ≥ 40
wage = $720 + 27x - $27*40 = 27x + 720 - 1080 = 27x - 360
Answer: 27x - 360; x ≥ 40
