Question

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

What is the function rule in slope-intercept form?
f(x)= ???

Answer 1

y = -1/2x + 1

Explanation:

• The slope is (0,1) and (2,0) if you count the ramp going down the positive numbers in the graph. Given that we have the slope, this is enough to start the problem.

`s = (\left(1-0\right))/(\left(0-2\right))\\s = (1)/(-2)\\s = -(1)/(2)`

• (The y-intercept is 1, because that is where the points last intercepted at.)

`y = -(1)/(2)x + 1`

Hope this helps!
