Well we know it can't be A nor C because we are doing multiplication.
Now you have to understand that you are just changing the order of the numbers.
The correct answer would be......
D
So first you would put these over a common denominator which is 96. You get this by multiplying by 9 and what you do to the denominator you must do to the numerator so you then get 45/96 and 63/96. Pelicans=45/96. Woodpeckers=63/96
Rewrite your function as a equation:
y=0.15x -75
Use the slope-intercept form to find the slope and y-intercept:
y=mx+b
Find the values of m and b using the form y=mx+b
m=0.15
b= -75
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 0.15
Y-Intercept: -75
To identify the rate of change (or unit rate) I would usually look for a pattern in the table or graph. For example, if I got a problem like what is the unit rate for price per pound of potatoes and they gave me a chart like this:
Price. Potatoes
1. 3
2. 6
3. 9
I could determine that the unit rate (or rate of change) would be that for every $1 you could get 3 potatoes
I hope this helped! Have a wonderful day! :-)
