Answer: The slope of the line is 
Step-by-step explanation:
The slope of a line can be calculated with the following formula:

Then, given the points
and
, you can identify that:

Knowing these values you can substitute them into the formula for calculate the slope:

Finally, evaluating, you get that the slope of that line is:

Answer:
Simple...
you have: x-3y=18
You want to convert it into slope-intercept form or y=mx+b form-->>>
x-3y=18
Isolate the variable-->>
x-3y=18
-x -x
-3y=-x+18
Now simply divide...
-3y/-3 = -x+18/-3
y=1/3x=6
Thus, your answer.
Answer:
40%
Step-by-step explanation:
Total amount is 15
6 out of the 15 amount are apples
Thus, 6/15 x 100 = 40%
Or
You could ask yourself, what number do I multiply by 15 to get to 100?
Then, multiply the top (numerator) by it.
The value of the numerator will give you the final % (percentage) due to percentage being out of 100.
Hope this helps!
