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 +

Explanation:

Step1: Identify slope (m)

The student reads 20 pages per day, so the rate (slope \( m \)) is 20.

Step2: Identify y - intercept (b)

By the start of the week, 50 pages are read, so the y - intercept (\( b \)) is 50.

Step3: Write linear function

Using slope - intercept form \( y=mx + b \), substitute \( m = 20 \) and \( b = 50 \). So the function is \( y=20x + 50 \).

Answer:

The linear function rule is \( y = 20x+50 \), so the value in the first box (for the coefficient of \( x \)) is 20 and the value in the second box (the constant term) is 50. If we only consider the coefficient of \( x \) as asked in the green box, the answer is 20.
