Question

iris picked a bucket of raspberries to make jam. the table shows the cups of raspberries left in the bucket, y, as a function of the number of batches of jam she makes, x. a) the rate of change is -2. it represents a decrease in the amount of raspberries in the bucket for each batch iris makes. b) substitute x = 1 and y = 16 into the equation. y = mx + b y = -2x + b? = -2(?) + b 1 16 batches, x raspberries left in bucket (cups), y 1 16 4 10 7 4

Explanation:

Step1: Identify x and y values

We know to substitute \( x = 1 \) and \( y = 16 \) into \( y=-2x + b \). So the left - hand side of the equation (where \( y \) is) should be 16, and the value inside the parentheses (where \( x \) is) should be 1.

Step2: Substitute the values

Substituting \( x = 1 \) and \( y = 16 \) into \( y=-2x + b \), we get \( 16=-2(1)+b \).

Answer:

The first blank (for \( y \)) is 16, and the second blank (for \( x \)) is 1. So filling in the blanks, we have \( \boldsymbol{16}=-2(\boldsymbol{1})+b \)
