Question: Plot the graph of y-2x=-3

(hint: rearrange the equation so it’s in 𝑦=𝑚𝑥+𝑐 form!)

 

Answer: Let’s rearrange this equation. Subtract 1 from both sides:

  y-2x=-3

Add 2x to both sides 

  y=2x-3

Using this equation we find the value of y. To do this we create a table, show below.

Now we have the following coordinates (-1,-5) , (0,-3), (1, -1), (2,1), (3,3)
