Write the equation y=-1/2x+3 in standard form. x + 2y -3 =0. x/2 + y/9 = 1/3. 4x-y+7=0. x + y/2 = -1/2. 3x-y-1=0. x - y/3 = 1/3.

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?
