the problem is to graph the equation below. 3x - y < 2 and x + y > 2 my solution is y = 3x - 2, y = -1x + 2 I,m lost at where my lines ar drawn. In y = 3x - 2 (y line is 3) and y = -1x +2 (y line is -1) or am I totaly lost. After continued effort I beleive 1st equation m...

Finding the slope and y-intercept for x = -9, I beleive is (-9, 0) and the slope is undefined. However what if you are looking for the slope and y-intercept of y = x? Hmmm. It is a vertical line, so you are right, slope is undefined. Now y=x is easy Rewrite it as y= 1*x + 0 ...

How do you get a slope if you only have the y-intercept. example: (0,5) and (-3, -4) To find slope: slope = (y2 - y1) / (x2 - x1) With your values: slope = (-4 - 5) / (-3 - 0) = -9/-3 = 3 I hope this will help and is what you were asking.

How would one write y = 2/3x -4 in standard form? First read: http://www.algebralab.org/studyaids/studyaid.aspx?file=Algebra1_5-5.xml Then: multiply both sides by 3 3y=2x-12 then move terms into standard form -2x+3y=-12 you could multiply both sides by -1 to get 2x-3y=12 but ...
