You can find the slope of that and this will be his wage rate.
Louis's rate is obviously 12 dollars per hour.
.............................More help was wanted...........................
Louis' earnings,
L(x), his earnings
x, number of hours worked
12, the slope of this linear equation; so this means .
Carl's earnings,
C(x), his earnings
x, number of hours worked
(x, C(x)) points: (3, 45), (5, 75), (8, 120), (10, 150).
Hopefully this forms all one single slope from point to point.

C(x) ---(part deleted)---- Carl obviously gets a rate of ---(part deleted)----.
If you work with Carl's data further, you will find also y-intercept is 0.
(for the graph: red for Louis, green for Carl)
