The mistakes you have are on both letter’s A and B so I wrote a note for you to look back on^^

Hi, so for A. You need to rewrite 19 as -19

And for B. You need to rewrite 15 as -15

Otherwise everything seems correct

I need help ? which linear function is represented by the graph?​
PilotLPTM [1.2K]
<h3>Answer: f(x) = (-1/2)x+1, choice B</h3>

=================================================

Explanation:

The diagonal line passes through 1 on the vertical y axis. So the y intercept is b = 1. This means the location of the y intercept is (0,1).

Start at (0,1) and move down 1 and to the right 2 to arrive at (2,0). This is another point on the diagonal line. The motion of "down 1 and right 2" is effectively the slope

slope = rise/run = -1/2

rise = -1, run = 2

The rise being negative means we have gone downhill as we move to the right.

With m = -1/2 as the slope and b = 1 as the y intercept, we go from y = mx+b to y = (-1/2)x+1

The last thing to do is replace y with f(x) to get f(x) = (-1/2)x+1 as the final answer.
