Jamila wants to play a game called “Guess My Line.” She gives you the following hints: “Two points on my line are $(1,1)$ and $(2,4)$."

1. What is the growth rate of her line? A graph of the line may help.

2. What is the $y$-intercept of her line?

   Answer (b):

   $y\text{-intercept}=(0,-2)$

3. What is the equation of her line?

   Hint (c):

   Use the rate of growth and the $y$-intercept to write an equation for the line. $y=mx+b$
