Write the equation of the line represented by the following table

Write the equation of the line represented by the following table
x | y
-3 |100
-2 |200
-1 |300
0 |400
1 | 500
2 | 600
3 | 700

Ok you have to get this table into the slope-intercept form, y=mx+b. So you can find the slope of the table by using m=change in y/change in x. So it would be 100/1 which is 100 so the slope is 100. So to find the y intercept just look where x=0. So the y intercept here is 400. So the answer to this is y=100x+400. To make sure this is correct just plug in all the x values to the equation and you will get the y value.

y = |100x + 400|, where the bars represent absolute value.
