Question

Find an equation for this table

Answer 1

y = -2x + 11

Explanation:

In order to determine the slope from a table, you pick any two points from the table and use the following formula to determine slope.

`(y2 - y1)/(x2 -x1)`

1) I have picked the following points

(4,3) (9,-7)

2) Plug in to the formula.

-7 - 3 / 9 - 4

-7 - 3 = -10

9 - 4 = 5

-10/5= -2

3) The slope is two, however to find the y intercept you use the slope to form a point slope form which will help determine the y-intercept.

4) The formula for point slope form is

y - y1 = m (x - x1)

Note: M represents slope.

Input the numbers.

5) y - 3 = -2 (x -4)

y - 3 = -2x + 8

y= -2x + 11
