Answer:
this is confused me so much is it supposed to be a trick or is that a actual question-
So in matt's equation, he made a mistake in the a transision from line 2 to line 3
in line 2: -4(-2)2
in line 3: -4(4)
the mistake is that -2 times 2 is not equal +4 it is equal to -4
also from lines 5 to 6 he made a mistake in order of opperations (mulit division then addition and subtract)
line 5: -10+30/5
line 6: 20/5
so he first subtracted 10 then divided, he should have divided then subtracted
so the equation should have equaled
Karen used the correct (-) times (+) property and the order of operations
so Karen is correct and Matt is wrong.
Answer:
Part A: Option A
Part B: Option C
Step-by-step explanation:
Given two points (7, 5) and (21, 15)
we have to find the slope of the line passing through above two points.
The slope of line can be calculated as


Option A is correct.
Part B: Also given another line with a slope that is one-third that of the slope of above and passes through the origin and the point
we have to find the point.

The equation of line becomes



The point which satisfies the above equation passes through the line.
Not satisfied
Not satisfied
Satisfied
Not satisfied
Hence, the line passes through the point (21, 5)
Option C is correct.
