You need parenthesis to write around a pair of coordinates.

For instance, you would write (5,7) instead of 5,7

The 5 is the x coordinate and 7 is the y coordinate. It tells us the exact location on the xy grid system. Think of it like an address or longitude/latitude.

Three equivalent ratios are shown on the graph
kvasek [131]

To plot more the points, we move up one and right two.

<h3>How to plot more the points?</h3>

The ratios are given as:

(1, 0.5), (2, 1), and (5, 2.5)

Calculate the slope (m) using:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{1 - 0.5}{2 - 1}

Evaluate

m = \frac{0.5}{1}

This gives

m = \frac{1}{2}

The above means

Vertical : Horizontal = 1 : 2

This means a vertical movement of 1, followed by an horizontal movement of 1

Hence, to plot more the points, we move up one and right two.

Complete question

Three equivalent ratios are shown on the graph. On a coordinate plane, points (1, 0.5), (2, 1), and (5, 2.5) are plotted. Starting on one of the plotted points, how can you plot more equivalent ratio points?

Find the perimeter of the triangle shown.Simplify your answer.Show all your work.
VashaNatasha [74]
Answer: 12 sqrt(5)

Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)

= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)

= 5 sqrt(5) is already simplified

= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)

Point A is located at (2, 6) and point B is located at (18, 12).
r-ruslan [8.4K]
From A-->B in a 2:3 ratio means that it's 2/(2+3) of the way up AB
So 2/5 of the x of AB = 2/5×(18-2) = 2/5 (16)
= 32/5 = 6 2/5 + the original x of A (2) = 8 2/5
2/5 of the y of AB = 2/5×(12-6) = 2/5 (6)
= 12/5 = 2 2/5 + the original y of A (6) = 8 2/5
Therefore the answer is:
(8 2/5, 8 2/5)
