Question 255071
It is as easy as plug in any number for x and solve for y.
The two easiest to calculate are usually
 when x=0 solve for y
and when y=0 solve for x

Or 
In the equation 5 is the y intercept when x=0 y=5
Plot that point 
The slope is -3/4 which means 
Either for every 3 that y goes down x goes across 4
OR for every 3 that y  goes up x goes back 4
It doesn't matter they are the same
So once you plot the y intercep (0,5) you can  do the above  

After you have two points connect the two points to form a line.
