Here we're interested in the circumference: C = pi*d. In this case C = 3.14*(28 inches) = 88 inches.
Now divide this 88 inches into 200 feet to get the # of revolutions ncessary to travel 200 feet.
200 feet 12 in
------------ * --------- = 2400 inches
1 1 ft
2400 inches
----------------------- = 27.2 revolutions (answer)
[ 88 inches/ rev ]
Given:
The inequality is:

To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,

The relation equation is:
...(ii)
On comparing (i) and (ii), we get


It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.

X= -3
Solution:
takeaway 4 from each side
x+3=0
subtract 3 from each side
x=-3
-9 is the answer to this equation
