-3y = 5x - 7
3y = -5x +7
now put x = 2
3y = -10 + 7
y = -3/3 = -1
first point is (2,-1)
now put x = -1
3y = 5 + 7
y = 12/3 = 4
second point (-1,4)

First rearrange the equation to the form y=mx+c.
\[-5x-3y=-7\rightarrow5x+3y=7\rightarrow3y=7-5x \rightarrow y=\frac{7}{3}-\frac{5x}{3}\]
Then you can read off the y intercept which is c
or just plugin values for x to get 3 points

Here is a graph so you can check your points

OpenStudy (anonymous):

now put x = 5
3y = -25 + 7
y = -18/3 = -6
so third point is (5,-6)

@MiMi
You can plot the three points given by me and join them by a line to get the graph....
