Help me please with those questions

Answer 1

Hi!

Let's start with number 9.

So we have to fill in the missing parts of the table by filling in the x/y values. 

Starting with the first blank, put 0 into the given equation. 

-2 · 0 + 3y = 6
simplify
0 + 3y = 6
subtract 0 from both sides
0 - 0 + 3y = 6 - 0
3y = 6
divide by 3 on both sides
y = 2

The first value is 2

Continue solving like this to fill in the whole table. 

-2x + 3 · 0 = 6
-2x + 0 = 6
-2x = 6
x = -3

-2x + 3 · 1 = 6
-2x + 3 = 6
-2x = 3
x = -1.5

The table completely filled in looks something like this...

   x   y
   0  2
  -3  0
-1.5  0

Now for question 10.

Basically, you just fill in the coordinates from the table. (0,2), (-3,0), and (-1.5, 0).

I have included an image that shows it drawn in. 

Hope this helps! :)
