Question

A functionf(x) is graphed on the coordinate plane.

What is the function rule in slope-intercept form?


Enter your answer in the box.


f(x)=

Answer 1

`-0.5x+1`

I took the test, I hope this helps anyone in the future!

Answer 2

y = -1/2x +1

Explanation:

The y intercept is 1 (this is where it crosses the y intercept)

(0,1) and (2,0) are two points on the line

The slope is given by

m = (y2-y1)/(x2-x1)

= (0-1)/(2-0)

= -1/2

The slope is -1/2

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = -1/2x +1
