In the equation y=mx+b, what does the x stand for? And, in the equation y=3x+6 how would I solve for y?
ladessa [460]

Answer:

x stays x in both equations so x stands for x

Step-by-step explanation:

y=3x+6

you can put this into a graphing caculator or draw it yourself.

6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value
