Answer: 0.625 pound
Explanation:
1 pound = 8 people,
y pound = 5 people
Cross multiply to get
1 x 5 = 8y
5 = 8y
y = 5/8 = 0.625 pounds
Step-by-step explanation:
Since 1/8 of his books are mystery and he has three of them, you would multiply 3 by 8 to find his total number of books which is 24.
Answer: y = 3x-8
------------------------------------------------
------------------------------------------------
Explanation:
The slope is 3, so m = 3
The given point is (3,1) meaning x = 3 and y = 1. The x coordinate is always listed first in an ordered pair. The general format is (x,y)
We'll use m = 3, x = 3 and y = 1 to find the y intercept
y = mx+b
y = m*x+b
1 = 3*3+b ... plug in m = 3, x = 3 and y = 1
1 = 9+b
1-9 = 9+b-9 ... subtract 9 from both sides
-8 = b
b = -8
----------------
So we're given m = 3 as the slope and we just found that b = -8 is the y intercept
So y = mx+b updates to y = 3x-8. This is the final answer.
----------------
Side Notes:
* The slope of 3 means rise/run = 3/1 indicating each time we go up 3, we move to the right 1
* The y intercept -8 is the location on the vertical y axis numberline where the graph crosses. The point (0,-8) is on this line.
