The simplified equation is y=3x-9, so the slope is up 3/right 1 and the y-int is -9. So here are three points: (-1,-12), (0,-9), (1,-6)
Answer:
Step-by-step explanation:
Plot 3 points on the coordinate grid and a straight line should go through all 3
You could start with x = 0 , then the y coordinate will be worked out:-
3(0) - y = 9 so y = -9 So thats one point (0, -9)
2 other points might be ( 3, 0) and ( 1, -6)
Its best to plot 3 points - if you make a mistake in working one out then you you probably won't get a straight line.
