Question

Write the slope intercept form of the equation for the line that is described in the following function table.

Answer 1

Answer:

y=mx+b

m = slope

b = y-intercept

To find slope we use the equation, change in y divided by the change in x. Let's use points (2, 2) and (3, 1).

(2-1) / (2-3) = -1

Meaning our slope is -1 and it will be going down.

Next, we have to find the y-intercept which is the value of y when x=0. When x is 0 y will be 4.

y=-1x+4
