That's point-slope form:
y - y1 = m(x - x1)
Where y1 is the y-value of a point on the line, x1 is the x-value, and 'm' is the slope.
So let's find out what goes in the first blank.
As we can see, they replaced 'x1' with -1, and one of our points have an x-value of -1, that point is (-1, -2), this means y2 must be -2:
y + 2 = m(x + 1)
Now let's find the slope between the two points.
m = y2-y1/x2-x1
m = (10+2)/(3+1)
m = 12/4
m = 3
So the slope is 3, plug that in:
y + 2 = 3(x + 1)

Answer:
it's answer is D. x+9
Step-by-step explanation:
x² + 5x - 36
= x² + ( 9 - 4)x - 36
= x² + 9x - 4x -36
= x ( x + 9) - 4( x + 9)
= ( x + 9 ) ( x - 4)

Answer:
(-1, -1)
Step-by-step explanation:
(1, -1) is a point in Quadrant IV whose radius (length of the ray from (0, 0) to the circle) is √2 (according to the Pythagorean Theorem).
If we rotate this ray 90° clockwise, we'll end up in Quadrant III, with the ray forming a 45° angle with each the x-axis and the y-axis.
This new point will be (-1, -1).
