Y = x2 + 3x - 5

y = x + 3

(-4,-1) (2,5)

Step-by-step explanation:

y = x^2 + 3x - 5

y = x + 3

Since they are both equal to y we can set them equal to each other

x^2 + 3x - 5 = x + 3

Subtract x from each side

x^2 + 3x-x - 5 = x-x + 3

x^2 + 2x - 5 = 3

Subtract 3 from each side

x^2 + 2x - 5-3 = 3 - 3

x^2 + 2x - 8=0

What 2 numbers multiply to - 8 and add to 2

4*-2 = - 8

4-2 = 2

(x+4) (x-2) = 0

Using the zero product property

(x+4) = 0 (x-2) = 0

x = - 4 x=2

Now we need to find y for each x

If x = - 4 y = - 4+3 = -1

If x = 2 y = 2+3 = 5

I'm not quite sure what u want, but here is what u probably wanted ...

y = 2x + 3x - 5

combine like terms: y = 6x - 5

then u can graph, using 6/1 as ur slope and - 5 as ur y int.

same thing with the other
