Answer:
The Answer is $4 or option (A)
Step-by-step explanation:
I took the test :)
Y2-y1/x2-x1
1-4/2-3
Slope is: -3/-1 or 3
Given:
The equation of a line is:

The line is dilated by factor 3.
To find:
The result of dilation.
Solution:
The equation of a line is:

For
,




For
,




Divide both sides by 2.


The given line passes through the two points A(0,5) and B(2,2).
If the line dilated by factor 3 with origin as center of dilation, then

Using this rule, we get


Similarly,


The dilated line passes through the points A'(0,15) and B'(6,6). So, the equation of dilated line is:




Multiply both sides by 2.



Therefore, the equation of the line after the dilation is
.
Answer:
Step-by-step explanation:
Divide
C, if there is an odd number of negatives it is negative, if there is an even number it is positive
