 Question 226098: Directions: Translate each sentence into an equation. Then find four solutions for each equation. Write the solutions as ordered pairs. Graph each equation. 1.) Some number is four more than a second number. Am I supposed to use y=mxtb or use a normal setup of equations? And when I did try y= 4(2)+b I only got 8. And I didn't know what to do with the two variables. So would I do the slope first? I didn't try that because they don't list four different numbers in the question; but I can't complete y=mxtb without knowing what b is. Thanks for your help!
