Question

in a reading challenge, a student has read 50 pages by the start of the week and plans to read 20 pages per day. write a linear function rule that represents the total number of pages read, y, after x days.

slope-intercept form
(y = mx + b)

(y = ?x + \box)

Explanation:

Identify the rate of change

Using the Linear Functions knowledge point

$$ m = 20 $$

Identify the initial value

Using the Slope-Intercept Form knowledge point

$$ b = 50 $$

Write the linear function rule

Using the Slope-Intercept Form knowledge point

$$ y = 20x + 50 $$

Answer:

In a reading challenge, a student has read 50 pages by the start of the week and plans to read 20 pages per day. Write a linear function rule that represents the total number of pages read, \(y\), after \(x\) days.

\(y =\) <blank>\(20\)</blank>\(x +\) <blank>\(50\)</blank>
