Question 1160537
{{{y=2x-2}}}-> here you have a linear equation, 

the graph is a line

a line is defined by two points

so, find two points

easiest way is to find x and y-intercepts 

{{{y=2x-2}}}......set {{{y=0}}} and find x-intercept 


{{{0=2x-2}}}

{{{2=2x}}}

{{{x=1}}}-> x-intercept is at ({{{1}}},{{{0}}})


{{{y=2x-2}}}......set {{{x=0}}} and find y-intercept 


{{{y=2*0-2}}}

{{{y=-2}}}-> y-intercept is at ({{{0}}},{{{-2}}})



plot these points and draw a line through


{{{drawing( 600, 600, -10, 10, -10, 10, 
circle(0,-2,.13),circle(1,0,.13),
 graph( 600, 600, -10, 10, -10, 10, 2x-2)) }}}
