Question

What is the unit rate of each point (10,2.4) (15, 3.6) (17.5, 4.2)

Answer 1

Answer:

0.24

Step-by-step explanation:

Given the points (10,2.4) (15, 3.6) (17.5, 4.2)

The unit rate is the slope of the line joining any of the two points.

Using points (10,2.4)  and (15, 3.6)

$Slope, m=\dfrac{3.6-2.4}{15-10} \\=\dfrac{1.2}{5} \\\\=\dfrac{6}{25}$

=0.24

Using points (10,2.4)  and (17.5, 4.2)

$Slope, m=\dfrac{4.2-2.4}{17.5-10} \\=\dfrac{1.8}{7.5} \\\\=\dfrac{6}{25}\\=0.24$

Therefore, the unit rate for each point is 0.24
