Step-by-step explanation:
Well in general, we can represent subtraction as:
"z" represents the difference, and it really just represents x with y taken away. So if we were to "give back" this y value, we should get "x".
This means that:
So one way to check, is adding the value that's being subtracted (y value) and the difference (z value), this should get you the value that is being subtracted from (x value). If you don't get the original value that's being subtracted from (x-value) then you know the answer you got is wrong.
Answer:
Options A, C, D are true.
Step-by-step explanation:
We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.
A. The points are (-4,-11) and (-2,-7).
Then the slope of the joining line is
B. The points are (5,6) and (-5,12).
Then the slope of the joining line is
C. The points are (0,-3) and (-4,-11).
Then the slope of the joining line is
D. The points are (0,-3) and (5,7).
Then the slope of the joining line is
Therefore, options A, C, D are true. (Answer)
