Answer:

Step-by-step explanation:
Proportional functions can be written as
, where
is some constant of proportional. Since directly proportional functions always pass through the origin, the y-intercept must be 0 (no additional number before or after
term). The only answers that fit this format are:

Answer:
3/20
Step-by-step explanation:
1/4 of 3/5= 3/20
hope its clear
Answer:
Increasing
Step-by-step explanation:
Remember that f(x) is the same as y in slope intercept form y = mx + b.
We don’t have a number for “b” which means the line goes across the origin.
Since 5 replaces m, that is the slope and since it’s positive, it is increasing.
Best of Luck!
Answer:
Step-by-step explanation:
Finding the answer to the second box is easy. Just look at where the line hits the y axis. That point is (0,5). Put a 5 in the second box.
-2
Now pick two points How about (0,5) and (2,1)
Givens
y2 = 5
y1 = 1
x2 = 0
x1 = 2
Formula
m = (y2 - y1) / (x2 - x1)
m = (5 - 1)/(0 - 2)
m = 4 / - 2
m = - 2
Answer
So the first box contains - 2
-2.5 because a positives opposite is a negative.
