Question 246732
y = 3x -5 is the equation of a line. 

Pick two values of x and solve for y in each case. Then draw the line that passes through the two points. 

For example when x=0, y = 3*0 - 5 = -5. So (0,-5) is a point on the line.

Choose another value for x and determine the corresponding value for y. 

Now that you have two points on the line you can draw the line through them.
