Can someone help me on this problem?

I need to write the equation of the line passing through the given pairs of points. I need to write the result in slope-intercept form, where possible:

(2, -3) and (2, 4)

Thanks,
Ashley
Evaluate the discriminant b^2-4ac. Then use the answer to state how many real-number solutions exist for the equation.
〖y=x〗^2+8x+16
