I think slope.

it needs to be graphed. I would just like the equation solved

First arrange the equation y=mx+b in this form

I'm not sure on how to do that. could someone do it step by step. I'm pretty confused

Easy way to graph a line: Make: 4y + 5x = -2 Into: y = mx + b
uri
  • uri
y = mx + b 4y=-5x-2
anonymous
  • anonymous
4y + 5x = -2 So you need to isolate the y To do that, you need to get rid of the 5x from the left side, so subtract 5x from both sides.

4y + 5x = -2 -5x -5x ---- ----
anonymous
  • anonymous
What do you get?
anonymous
  • anonymous
4y=-5x-2
anonymous
  • anonymous
yes
anonymous
  • anonymous
Now divide both sides by 4
anonymous
  • anonymous
4y=-5x-2 -- -- -- 4 4 4 What do you get?
anonymous
  • anonymous
so it's y=-5/4x-1/2?
anonymous
  • anonymous
\[y = - \frac{ 5 }{ 4 }x - \frac{ 1 }{ 2 }\]
anonymous
  • anonymous
yes.
anonymous
  • anonymous
how would I graph that?
uri

-5/4x is the slope
anonymous
  • anonymous
Easy: Now that it is in y = mx + b, Graph is a line with point (0,b) and slope m
anonymous
  • anonymous
I need to graph it as a line though
anonymous
  • anonymous
So: \(Slope = m = -\frac{ 5 }{ 4 }\)
anonymous
  • anonymous
Jorge, yes we know that it is a line and that is what we are going to graph.
anonymous
  • anonymous
b is the y-intercept, and b = -1/2 then: (0 , -0.5) slope = rise / run = -5 / 4
