The correct answer would be the first choice, y=3/2x+3.
Since the line enters the y-axis at (0,3) the y-intercept of the equation would be 3 (as according to the y=mx+b format where b is the y-intercept and m is the slope). The slope would be 3/2 since when you find two perfect points (I used (0,3) and (2,6)) and you use the rise over run method (move up 3 from (0,3) and 2 to the right to get to (2,6)), your slope is 3/2.
A) from 2 to infinity
B) from -infinity to -3
C) -3 to 2
D) -infinity to -3 and 2 to infinity
E) -infinity to infinity
F) no because the slope is linnear in 2 stops but has a different slope in both spots meaning it can’t be a linnear function or an exponential funtion
Here's what you need to know in order to answer this:
1 gallon = 128 fl oz
and
1 day = 24 hours.
Use those facts to invent fractions equal to ' 1 '.
Then use those to change the units of the "11 fl oz per hour".
You can multiply them ... since their value is ' 1 ', they won't
change the value of the "11 fl oz per hour", only the units.
(11 fl oz/hr) x (24 hr/da) x (1 gal / 128 fl oz)
= (11 x 24 x 1 / 128) (fl-oz - hr - gal) / (hr - da - fl-oz)
= 2.0625 gal/da
Answer: 30 ft tall
Step-by-step explanation: X= the height of the tree in feet
27/x = 4.5/5
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
Answer: A.) It is a linear function because there is a constant rate of change in both the input and output values.
============================================================
Explanation:
Note how x is decreasing by 3 each time
- -2-3 = -5
- -5-3 = -8
- -8-3 = -11
At the same time, y is also decreasing by 3 each time
This means we have a linear function. We have,
slope = (change in y)/(change in x)
slope = (-3)/(-3)
slope = 1
Recall that slope is another term for rate of change, so a constant slope means we have a constant rate of change.
----------------
Another way to find the slope is to pick any two points from the table and use the slope formula
m = (y2 - y1)/(x2 - x1)
You should find that any two points you pick will lead to a slope of 1. I recommend you try out all possible pairs to help convince yourself the slope is 1.
