Answer:
y = -x + 2
Step-by-step explanation:
If you know the slope and a point on the line, then you can find the equation with an equation:
(y - y1) = m (x - x1)
We have our slope, -1; we have a x1, -2, and a y1, 4, so we're all set to find the equation. Plug in the numbers:
y - 4 = -1 ( x + 2 )
y - 4 = -x - 2
y = -x + 2
Our equation is y = -x + 2
I believe the answer is B. This is because a perfect square is an integer that is the square of another integer. For instance, 9 is a perfect square/square number because it equals 3^2 [3*3]. And in this case when B is square rooted, you then get the value that makes it a perfect square.
I’m pretty sure, but I’ll check on it also. It’s been awhile .
