T=0 I guess
Hope this helps :)
Sorry if this is wrong
Question 1
Let the scale factor be k.
Then, we have the mapping
This implies that:
We equate any corresponding component find the value of the scale factor k.
6k=2
Hence the scale factor is
Question 2:
The midpoint of any two points can be calculated using the formula;
We want to find the midpoint of (-8, 5) and (2, -2).
The midpoint is:
The answer is 20x + 5y = 50
If u move the 20x over u get:
5y=-20x + 50
Solve for y by divided by 5
This gets y=-4x + 10
Now the answer is in slope intercept form: the -4 is the slope and 10 is the y-intercept
