The slope of a line is calculated by dividing the one y portion of the line by one x portion of the line. In this problem we have two points which can indicate us one portion of the y axis and one portion of the x axis. If we have two points of one line, then we can calculate its slope:
Point one (x1, y1)
Point two (x2, y2)
then the slope can be calculated as:
m = (y2 - y1)/(x2 - x1)
So lets use our data:
Point one (2, 10)
Point two (5, 8)
then the slope can be calculated as:
m = (8 - 10)/(5 - 2<span>)
</span>m = -2/3
therefore the slope is negative and is -2/3
The volume formula is length x width x height. 7x5x12=420 cubic inches
The answer is .277
Why:
Because first of all there are 26 letters in the alphabet then 10 numbers are given. so add those together; 26+10= 36
So 36 is the total and the fraction is 10/36
then divide
10/36= .277 about
