Question

part c
let ( x ) represent the number of weeks, and ( y ) represent the price. write an equation of the line.
enter the correct answer in the box.
show hints
( y = square )

Explanation:

Step1: Identify ordered pairs

The pairs are $(7,8), (4,5), (1,2), (0,0)$

Step2: Calculate slope $m$

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{8-5}{7-4}=\frac{3}{3}=1$

Step3: Find y-intercept $b$

Use $(0,0)$: $0=1(0)+b \implies b=0$

Step4: Write line equation

$y=mx+b$

Answer:

$y = x$
