Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cell phone bill for x minutes. Using points (230, 17.45) and (370, 19.55):
For 150 minutes:
y = 0.015(150) + 14 = 16.25
For $21.50:
21.50 = 0.015x + 14
x = 500
It would take 500 minutes for the cost to be $21.50.

Answer:domain: -infinity <\= × >\= +infinity
Range: -infinity <\= y >\= +infinity
Step-by-step explanation:the arrow at the end of the line means it is continuing infinitely in that direction, so the the line is always increasing and decreasing in y and x values.
