Hello :
the equation 3x^2+4x-7=0 has 2 solutions because : ac <span>< 0
a = 3 b=4 c= -7
</span>Δ = b²-4ac....... b² ≥ 0 and -4ac > 0 ..... (ac < 0 )
coclusion : Δ>0.....(2 solutions)

The slope, m, is given by the equation m = (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are points on the graph. Thus:
m = (-18-(-18))/(-15-12)
= (-18+18)/-27
= 0/27 = 0
Therefor the slope is 0
