Try this option:
the line y=-2x-3.
Explanation:
if to see the pair of equations: y=x²+x-2 and y=-3x-3, ⇔ x²+x-2=-3x-3, ⇔ x²+4x+1=0, D>0, then they have two common points.
if to see the pair of equations: y=x²+x-2 and y=-2x-3, ⇔ x²+3x+1=0, ⇒D>0, then they have two common points.
for y=x²+x-2 and y=2x-3: x²+x+1=0, D<0, it means, that these equations have no common points.
for y=x²+x-2 and y=3x-3: x²-2x+1=0, D=0, it means, that these equations have the only common point.

answer: y=2x-3.

Every triangle in the figure at right is equilateral. What is the measure of ∠AGE?
Andrew [12]

Answer:

120°

Step-by-step explanation:

All the angles of an equilateral triangle are equal, and hence have a measure of 60°.

∵ ∠AGF is a part of equilateral Δ AGF, m∠AGF = 60°.

∵ ∠FGE is a part of equilateral Δ AGF, m∠FGE = 60°.

Also note that ∠AGE = ∠AGF + ∠FGE.

⇒ m∠AGE = m∠AGF + m∠FGE

⇒ m∠AGE  = 60° + 60°

                    = 120°.
