Consider the fuction f(x) =-2/3x+1 what is f(3)

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?

Solve the equation. then check your solution 8=1.88+a
