Question 128718
What is meant here is that you must generate the three points using the given equation!
Then you plot these three points on coordinate graph paper and join the three point with a straight line.
Step 1: Generating the points using the equation {{{y = (3/4)x + 3}}}
Assign a value to x (the independent variable), it can be any value you like but if you keep it small, the calculations will be easier. Then find the corresponding value of y (the dependent variable) by substituting your value of x in the equation.
Start with x = 0
{{{y = (3/4)x+3}}}
{{{y = (3/4)(0)+3}}}
{{{y = 3}}}
So here's your first point: (0, 3)
Now let x = 4
{{{y = (3/4)x+3}}}
{{{y = (3/4)(4)+3}}}
{{{Y = 3+3}}}
{{{y = 6}}}
Here's your second point (4, 6)
Now try one yourself with x = 8...you should get y = 9

Now with the three points on your coordinate graph paper, you can draw the line through them and you have your graph. Here's what it should look like:
{{{graph(600,400,-5,5,-5,5,(3/4)x+3)}}}
