What is the graph of 7x+y=-7 ?

max2010maxim [7]

To make it easier to graph this equation, you can manipulate it to get it in slope-intercept form. You'd do that like so:
7x + y = -7

0 10 17

1 11 19

2 14 21

3 19 23

4 26 25

3.5 22.25 24

2.5 16.25 22

1.5 12.25 20

0.5 10.25 18

We see the pattern that it is increasing with only a unit. The last given data is mid of the last two values that is 3 and 4.

So the next value would be the mid of the next last two values that is 2 and 3 and will be 2.5

Now it is moving in the reverse direction in the same pattern with a difference of a unit.
