Answers for the chart left to right
(-2, 4 1/2) (-1, 4) (0, 3 1/2) (1, 3) (2, 2 1/2) (3, 2)
Step by step
First I put our equation into y intercept form
2y = -1x + 7
Divide both sides by 2 to isolate y
2/2 y = -1/2x + 7/2
y = -1/2x + 3 1/2
Now we fill in your chart
From this we see the y intercept is at 3 1/2, so at (0, 3 1/2) is our coordinate on the y axis.
Enter this on your chart at 0x.
From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0
3 1/2 + -1/2 = 3, (1, 3)
3 + -1/2 = 2 1/2 (2, 2 1/2)
2 1/2 + -1/2= 2 (3, 2)
Moving left from 0
3 1/2 - -1/2 = 4 (-1, 4)
4 - -1/2 = 4 1/2 (-2, 4 1/2)
Now you can graph your points
