Using the quadratic equation formula: x = -1/4 and x = 2/3
factors are (4x + 1)(3x - 2) so y = 0 when x = minus a quarter and x = two-thirds
y=-5x+8 the slope is -5.
To work out y=-5x-10 you can plot a graph.
-5
First factor is x, but we need to know the sign of 5x in your equation...

(5x + 3)(4x^2 + 1)
x3 + 12x2 - 5x = x(x2 + 12x - 5) = x(x + 6 - √41)(x + 6 + √41)
y = 5x + 2
