The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour
<h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the total cost of hiring for x hours. Hence:
- Using the points (0, 125) and (15, 950)

The rate of change is $55 per hour. The means that the hourly rate of the designer is $55 per hour

B) 7/10
It is B because there are 7 out of 10 possibilities that you would get a number greater than 7 or an odd number.
y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
