Question

1. damaris ate 10 dolphins and eats 2 dolphins each day. what are the slope and y-intercept of the word problem?

a m=8 b=8
b m=12 b=12
c m=2 b=10
d m=10 b=2

1. damaris ate 10 dolphins and eats 2 dolphins each day. what is the slope-intercept formula for this word problem?

a $y=2x+10$
b $y=2x$
c $y=10x+2$
d $y=10x$

Explanation:

Step1: Identify slope (rate of change)

The daily rate is 2 dolphins, so slope $m=2$.

Step2: Identify y-intercept (initial value)

Initial number is 10 dolphins, so $b=10$.

Step3: Write slope-intercept formula

Use $y=mx+b$, substitute $m=2, b=10$.
<Expression> $y=2x+10$
