Whenever you have straight lines on a graph they mean that that they only have either an x value or a y value. Normally you would have both, right?
so,
1. what is k doing? Its a horizontal line so it will be all y values at the point where it crosses the y axis. Here it looks like it crosses at the 8 mark so the value of this is y=8
2, line 1 crosses the x axis so it is all x values. here it crosses at 1 so its equation is x=1 the line parallel to it crosses x at 7 so its equation is x=7
The last line to describe crosses y at 2 so its equation is y=2.
3. The area is easy just count all the squares inside the figure. Or the formula is length times width.

The results of joes survey show that baseball is the favorite sport for 18 out of 25 people. What percent do not like sports?

charle [14.2K]

well if 18 out of 25 like it, then the remaining 7 doesn't like it, namely 7 out of 25.

if we take 25 to be the 100%, what is 7 off of if in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 25&100\\ 7&x \end{array}\implies \cfrac{25}{7}=\cfrac{100}{x}\implies 25x=700\implies x=\cfrac{700}{25}\implies x=28$
