Question 272115: Hi
I'm supposed to put this into slope-intercept form. (10,-3) (-8,-9)
Would I use m= y2-y1 over x2-x1 to get the slope? Then do I need to use the point-slope formula y-y1=m(x-x1)? I'm not sure if I'm ending up with the right answer. y=1/3x-19/3
Thanks

Question 272113: Hi
I need to change this into Slope-intercept form. I'm thinking this is y=mx+b??? 2y+8=9+9x I'm getting y=9/2x + 1/2. Am I doing this right?
Also, 6-(4y+3x)=6(x-y) In Slope-intercept, I'm getting y=9/2x-3....Am I doing this right?

Question 272303: Can someone explain the steps to solve for y for graphing for linear equations? I am having trouble with the equation y = -1/2x -4. I can solve for y without any problem with the variables given for x, but for some reason I am not understanding how to solve for x when given the variable for y. For example, I know that y is -1 and that the answer is -6, but I cannot seem to get the correct answer on my own.
