Find the solution to the system of equations y=2x+1 y=x^2+2x-15

x = 4 OR x = -4

Step-by-step explanation:

To find the solution, you can set both equations equal to one another:

(1) y=2x+1; (2) y=x^2+2x-15

2x+1 = x^2+2x-15

Then solve for the x-values that make this true.

2x+1 = x^2+2x-15

1 = x^2 - 15

16 = x^2

x = 4 OR x = -4

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
