lars. I think you’re the gasoline is $3.75 per gallon, and a car wash is free if you get at least 10 gallons. Which gas station gives Daniel better deal
2 is the slope so the slope perpendicular to that is -1/2 (negative reciprocal) -5=-1/2(9) 9*-1/2=-4.5 and -4.5 - 0.5 = -5 so the equation for the line is y=-1/2x -0.5
