5x-4y=-18 what is the three point on a graph for this equation

(1)Draw the "y" line . It goes up and down. 
Make sure to mark the centimeters or quarter inches with little nobs. 
Start at -20 and go to 10 
(2)Draw the "x" line. it goes side to side. 
place the x line at the zero point of the y line. I'm sure you will see your paper looks like the letter "t". Perfectly at a right angle. you could use the corner of a book to square it. 

Now for the maths 5x - 4y = -18. The most important symbol here is the "=" sign. 
(3) rearrange the equation so that y is on one side of "=" and x is on the other side. 
Remember if you add 10 to one side the of "=" , then for it to be equal, add 10 to the other. side also 
so add 4y to both sides. add 18 to both sides . divide the whole of each side by 4. 
5x - 4y + 4y + 18 = -18 + 4y + 18 
1.25x + 4.5 = y 
(4) now write down on a peace of scrap paper, x=1, y= 5.75, x=2 y= ___ , x=3 y= ___ 
(5) remember BEDMAS, and put 1 in the place of x and calculate what y is . 
(6) get your ruler , line up x = 1 (ruler is going up and down) and draw a spot on what y = . Get two rulers if you must. 
(7) 
hey presto, you got your three points on a graph.

Ibelieve the answer would be b.
