Answer:
all are functions except Relation 2
Step-by-step explanation:
If any input value (first of an ordered pair) is used more than once, the relation is not a function. Output values can be used as often as you like.
Only Relation 2 is not a function.
The true statement about the graphs of these two lines are The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other. First option is right
<h3>How to solve for the lines</h3>
The equation of the graph is in its intercept form. This is given as y = mx + b. m is the slope while be is the intercept.
The slopes of the lines have \been given as -8 and 1/8. These numbers are negative reciprocals when they are multiplied,
-8 * 1/8
= -1
Hence the first statement is right.

Answer:
10
Step-by-step explanation:
if you take 10 note cards and cut in half you will have 20 pieces
Scale factor = size of image /size of preimage
= mA'B' / mAB
= 18/6
= 3
Your choice of scale-factor = 3 is correct! Well done!
