Gelneren [198K]

Answer:

a. (1,0.25)

b. y = 0.25x

Step-by-step explanation:

Given

The data in the table

Solving (a): The coordinate that represents the unit rate

The unit rate is when its 1 pound

This is so because the unit rate is dollars per pounds.

<em>Hence, the coordinate is </em>(1,0.25)<em></em>

Solving (b): Equation of the graph

First, we calculate the slope (m)

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

Where:

(x_1,y_1) = (1,0.25)

(x_2,y_2) = (4,1.00)

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

m = \frac{1.00 - 0.25}{4 - 1}

m = \frac{0.75}{3}

m = 0.25

The equation is then calculated as thus:

y - y_1 = m(x - x_1)

This gives:

y - 0.25 = 0.25(x - 1)

y - 0.25 = 0.25x - 0.25

Make y the subject

y = 0.25x

<em>Hence, the equation of the graph is: </em>y = 0.25x<em></em>
