 Question 134823: I know I have to set this to Y= in order to find the points for the x and y intercept, but honestly my brain just quit on me. I need to graph the following: Graph 2x-5y=10. I have 2x-2x-5y=10-2x -5y = -2x+12 -5y/-5= -2x+12 --------- -5 My answer was y=2/5x+12 But I know that's not right. The correct answer is y=2x/5+2 that is y= 2x over 5+2 Please help! Ever have one of those days your brain refuses to do anything but be jello?? lol BTW-This is not from a textbook. It is a worksheet. Click here to see answer by stanbon(57303)
