Question

How do I write the equation of the line represented by the following table?

X= -3, -2, -1, 0, 1, 2, 3
Y= 100, 200, 300, 400, 500, 600, 700

Answer 1

The slope of the line is 100, because y is changing by 100 each time
x changes by 1. The y-intercept is 400, because when x = 0, y = 400.
So, the equation is y = 100x + 400.
