Question

Maddie is reading a graph of equivalent ratios. One point on the graph is (4, 5). Maddie says (10, 8) is also on the graph. Is Maddie correct? Explain why or why not.

Answer 1

Equivalent ratios are ratios that can be simplified to the same value.

Maddie's claim is incorrect.

The points are given as:

$\mathbf{(x,y) =(4,5) (10,8)}$

For a point (x,y); the ratio is calculated as:

$\mathbf{k = \frac yx}$

For point (4,5), we have:

$\mathbf{k = \frac 54}$

$\mathbf{k = 1.25}$

For point (10,8), we have:

$\mathbf{k = \frac{8}{10}}$

$\mathbf{k = 0.8}$

By comparison:

$\mathbf{1.25 \ne 0.8}$

Hence, Maddie's claim is incorrect.

Answer 2

Answer:

No, Maddie is not correct. The points (4, 5) and (10, 8) do not represent equivalent ratios. The ratio 4 to 5 is not the same as the ratio 10 to 8. She read the numbers of the ordered pair in the wrong order. She should have said (8, 10) is on the graph.
