Brad delivers packages for a flat rate of $9 per hour. chelsea works for a competitor and she earns $4 per hour plus $0.50 per delivery. this can be represented as a system of equations as shown below where h represents the number of hours, s represents the salary, and d represents the number of deliveries.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
