Once you have the slope, identify a point on the graph and use this formula

but when I do here different answer y = (2.25) - 3 (2.25)^1/2
I know my dear it will come in that equation but when I do here y = (2.25) - 3 (2.25)^1/2 I got diffrent answer .
What do you mean "when I do here"? Are you saying you get something other than 2.25 for y? If so you are doing the arithmetic wrong!
