The answer is “Two and a half pounds of dark chocolate cashews cost $37.50”

Since 1 pound of cashews costs $15, you multiply 15 by 2, to get $30, then you multiply 15 by .5 since you still have half a pound left, which then gives you $7.5, then you add 30 to 7.5, which gives you the answer of $37.5

Find the slope of the line that passes through the two points below."<br> (7,-1) and (9,0)

Answer:

1/2 or 0.5 (same value, different form)

Step-by-step explanation:

Ok...since I can't actually graph it, we can make a table out of it....

x y

7 -1

9 0

From -1 to 0, we add 1 (this is for the y section)

From 7 to 9, we add 2 (this is for the x section)

Now all we have to do is divide the y with the x

y/x = 1/2

The slope will be 1/2 (fraction form) 0.5 (decimal form)

Hope this helped!

The constant is 3.

This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
