find the points of intersection of the following pairs of equations.
a. y=x^2 and y=x +2
b. y=x^2 and y=8x^2
c. y=x^2 and x=y^2

a. Substitute (x + 2) from the second eq., simplify and solve for x. Then solve for y.
The other two equations are done the same way.
a. x+2 = x^2
x^2  x  2 = 0
(x  2)(x + 1) = 0
can you finish it?

for for like a. it would be (2, 4) and (1, 1)?
