Question

solve y=-2x^2 for y=mx+b

Answer 1

that actually can't be done. y=mx+b is a basic equation for a straight line, but y=-2x^2 is a parabola (more specifically, it opens downward and is skinnier than the basic y=x^2 function)

Answer 2

so as this bing a problem in a text book, the answer would be no solution?

Answer 3

correct. y=mx+b is an equation of a straight line, and there is no way to model a parabola as a straight line. if you go to an online graphing calculator, you can type in the y=-2x^2 function and see that it isn't a straight line. =]

Answer 4

thanks

Answer 5

no problem =]
