Answer:
(12, 9)
Step-by-step explanation:
I am assuming it was rotated about the origin.
180 degrees clockwise would give the point ((9, 12).
Then if this point is roated 90 degrees anti-clockwise it would end up at the point (12,9)
Answer:

Step-by-step explanation:
using the image attached as reference
(-4,-1) - the -4 becomes x1, and the -1 becomes y1
(5,7) - the 5 becomes x 2 and the 7 becomes y2
plug this information into the equation
7-(-1)
m=----------
5-(-4)
solve
8
m=----------
9
so your slope would become 8/9
Answer:
y = 1/2x + 1
Step-by-step explanation:
The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.
The line crosses the y axis at positive 1 and that is the y-intercept.
