Question 194649
to plot a graph
:
simply give a value to x and solve for f(x)
:
if x=1 then f(x)=4(1)+2=6--->so we can plot the coordinate(1,6)
if x=0 then f(x)=4(0)+2=2--->another coordinate(0,2)

this is enough to draw our line but you may do a few more just to be sure you havent made a mistake
:
{{{graph(300,300,-10,10,-10,10,4x+2)}}}
