Question 41540
First of all we need to pick a value for x.

 X|Y
_____
 0|2
 4|5

If we suppose x is equal to 0 then the equation would look like:

{{{y=(3/4)(0)+2}}}
{{{y=0+2}}}
{{{y=2}}}

If we suppose x is equal to 4 then the equation would look like this:

{{{y=(3/4)(4)+2}}}
{{{y=(12/4)+2}}}
{{{y=3+2}}}
{{{y=5}}}

Now we have 2 points so we can draw the line.

{{{graph( 400, 400, -10, 10, -10, 10, (3/4)x+2 )}}}
