Answer 1

The hourly rate of plumber T is $87 per hour and have an initial cost of $41.

Linear equation

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the initial amount.

From the table, using points (1, 128) and (2, 215):

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-128=\frac{215-128}{2-1}(x-1)\\ \\y= 87x+41$

The hourly rate of plumber T is $87 per hour and have an initial cost of $41.
