A couple more i'm having problems with.(adsbygoogle = window.adsbygoogle || []).push({});

First with linear intercepts.

Find the y-intercept of a line going through (3, 0) and having a slope of -5

y=mx+b

m = -5

And from then on, I don't know how to continue with this problem.

------

Now, completing the square.

Solve: Solve: 4x^2 - x - 5 = 0

Steps:

4x^2 – x = 5

x^2 - 1/4x = 5/4

-1/4 --> 1/16

x^2 - 1/2x + 1/16 = 5/4 + 1/16

(x-1/4)^2 = 21/16

Solve for x now right? Well i think i already messed up in one of my earlier steps. I need help.

Thanks for any help...
