Answer: Plot a straight line through (0,-3) and (3,0)
Diagram is shown below.
Step-by-step explanation:
Plug in x = 0 and solve for y.
x - y = 3
0 - y = 3
-y = 3
y = -3
We have x = 0 lead to y = -3. Therefore, the point (x, y) = (0, -3) is on the line. It is the y-intercept.
Let's plug in y = 0 and solve for x.
x - y = 3
x - 0 = 3
x = 3
Therefore, the point (3, 0) is also on the line. This is the x-intercept.
The straight line goes through (0, -3) and (3, 0)
Check out the graph below. I used GeoGebra to make it, but Desmos is another option you can use.
