Question 721038
{{{ y+2=3(x+1)}}}


{{{ y=3(x+1)-2}}}

{{{ y=3x+3-2}}}

{{{ y=3x+1}}}...you have linear function and you need two points to graph it; so, take two values of your choice for variable {{{x}}} and find {{{y}}}

{{{x}}}|{{{y}}}

{{{0}}}|{{{1}}}......{{{ y=3*0+1=1}}}

{{{1}}}|{{{4}}}......{{{ y=3*1+1=4}}}

plot these points and draw a line through

{{{drawing(600, 600, -10, 10, -10, 10,grid(1),circle(1,4,0.2),circle(0,1,0.2), graph( 600, 600, -10, 10, -10, 10,locate(1,4-.2,"(1,4)"),locate(0,1-.2,"(0,1)"), 3x+1)) }}}
