Factor completely: −4x2 + 16x − 24

First, you need to see which number all of these numbers have in common, and that is number 4. So, let's start:

-4(x2 - 4x + 6)

The expression in the brackets cannot be factored further, which means that the answer above is the complete factor of the original expression. Hope it helps. :)

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
