Question 54385
This equation is in slope intercept {{{highlight(y=mx+b)}}} where m=slope={{{rise/run}}} and (0,b)=y-intercept (where the line crosses the y-axis).
{{{y=(3/4)x+2}}} has a y-intercept (0,b)=(0,2) and slope=m=3/4.
Plot (0,2)  from that point use your slope m=3/4 and rise up 3 and run right 4.  Plot your second point there.  (It should be (4,4) if you did it right.)
Connect the dots and you have a graph that looks like:
{{{graph(300,200,-10,10,-10,10,(3/4)x+2)}}}
Happy Calculating!!!
