Question

-3y=-x-7 graph the eqaution by plotting three points? Please help, thank you.

Answer 1

This is a line. A line follows the same path no matter what. In fact, you can draw a line if you know just 2 points that line on that line. How do you do that?
Well substitute three x values and find out what the corresponding y values are.
First: -3y=-x-7 can be converted into -3y = -(x+7) so
\[y=\frac{ x+7 }{ 3 }\] Now this makes it a lot easier.
Let x be any 3 values. x = -1, 0 and 2 say
When x = -1, y = 6/3 = 2
When x = 0, y = 7/3
When x = 2, y = 9/3 = 3
So there are our three points (-1,2), (0,7/3) and (2,3)
Plot them join them and you have a line.

Answer 2

no fractions are allowed

Answer 3

Well then choose another x value that generates an integer y value. x = 5 gives
y =12/3 = 4, (5,4) being the point. Technically you only need 2 points to make a line.
Fractions might make it harder to plot but they still lie on that line if they satisfy the equation
