Question

Use the coordinates of the labeled point to find the point-slope equation of

the line.
(2, -1)

Answer 1

Answer: (C)
`y+1=-2(x-2)`

Explanation:

Slope: y = mx +b

By looking at the graph we can see that the slope has a rise of 2 and a run of -1 (aka. -2x) We can also tell that this has a y-intercept of 3

So our slope is: y = -2x + 3

Now you just have to find the answer that matches.
