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.

Step-by-step explanation:

You can do the product by multiplying starting from the left.

3 * 3 * 3 * 3 * 3 =

= 9 * 3 * 3 * 3

Of the dogs at the dog show,

Olin [163]

So, let's say that all the dogs had a number of x.

then 1/12 x were the Hound Group dogs.

then, out of the Hound Group,, that is 1/12 x, 3/10 were English Foxhounds.

For this, we need to multiply the fractions:

$\frac{1}{12}x* \frac{3}{10} = \frac{3}{120}x =\frac{1}{40}x$

so of all the dogs at the show, the English Foxhunds were a 1/40 fraction,

Write the corresponding sides ad equal ratios

Notice the corners; the corner on each triangle with one line is equivalent, and the same goes for the corner on each triangle with two lines, and the corner on each triangle with three lines. this is just a way to know which angles match up!

this means the answer would be:

D!
