Question

If a system including the quadratic equation representing the parabola and a linear equation has no solution, which linear equation could be the second equation in the system? A. 1/2x=y+4 B. 2x-y=0 C.y=6 D.y=2x+6​

Answer 1

D. y = 2x + 6.

Explanation:

The required equation would not intersect the parabola at any point.

The only one to fit that is D.

Answer 2

9514 1404 393

Answer:

D. y=2x+6​

Explanation:

The line cannot intersect the parabola if it has a y-intercept greater than 5 and a suitable slope. The only sensible answer choice is ...

y = 2x +6
