Okay, you want to graph it?

It follows Slope-Intercept Form, y=mx%2Bb, wheresystem%28m=slope%2Cb=Yintercept%29

Let Fx=0:
y=3x%2B2 ---> y=3%280%29%2B2
y=2, Y-intercept (0,2)

Let Fy=0:
y=3x%2B2 ---> 0=3x%2B2 ---> -2=3x ---> -2%2F3=cross%283%29x%2Fcross%283%29
x=-2%2F3, X-intercept (-2/3,0)

Knowing the Slope = 3%2F1=Rise%2FRun=DELTA%28y%29%2FDELTA%28x%29

We Rise 3 steps from the Y-intercept (0,2) = (0,2+3) and Run 1 step to the right (0+1,2) ------> (1,5) (next point).


Going to the next point, we Rise again 3 steps from the previous point (1,5)= (1,5+3) and Run 1 step to the right (1+1,5) ----> (2,8) (next point).


Going back to the Y-intercept, (0,2), we moved 3 steps down on the Y-axis "-3" = (0,2-3) and moved 1 step to the left on the x-axis "-1" = (0-1,2) -------> (-1,-1) (next point)
*Remember, %28-3%29%2F%28-1%29=3%2F1



Then from point (-1,-1), moved again 3 steps down on the Y-axis "-3" = (-1,-1-3), and moved 1 step to the left again on the x-axis "-1"= (-1-1,-1) -----> (-2,-4) (next point)...

Just continue the rest and you can draw the line thru the points.

Thank you,

You cannot solve that equation. There are an infinite number of real number ordered pairs that satisfy the equation. You can draw a graph of the solution set, namely a line with slope 3 passing through (0, 2). Is that what you wanted?
