Step-by-step explanation:
The equation is in 'point-slope' form.

This means we can identify the point that was used in the equation.

(6,4) would be a solution to the equation given.
Hope this helps.
I also need help on this question. Someone please help out
It can be factored.
We need two numbers that multiply to -12 and add to -4, so are two terms would be -6 and 2.
(x - 6) (x + 2) = 0
x = 6
x = -2
