they are loopy things that appear on a graph
they usually have $$x ^{2}$$
and look like this

Find the y-intercept for the parabola defined by this equation:
y=-6x^2-7x-2

anonymous · Answer

Alright so your equation gives you 1 y point for any x point you input into the equation. For example we know that when x is 1 y is -15. The y-intercept is simply where your x, value is 0. Whenever x is 0 we know that that the why coordinate is purely on the y-axis. 

So the way to figure this out is substitute x with 0 giving us
y = -2

So the y-intercept is -2! or rather (0,-2)
