Write the equation for slope from 2 points.
What does the y intercept tell us?
The y intercept tells us where the line crosses the y axis. It can be a starting value. This is where x = 0.
Slope =
(y_2-y_1)/(x_2-x_1)

Ellie was responsible for testing the effectiveness of antibiotics in her lab. She was wondering how the effectiveness of a new antibiotic changed with the amount used. She prepared 18 petri dishes in her lab. To six of the petri dishes, she added no antibiotic; to another six, she added a low dose of the antibiotic; and to the remaining six, she added a high dose of the antibiotic. Then she added an equal amount of the same bacteria to each dish. She allowed the bacteria to grow overnight in the same conditions. The next day, Ellie counted the number of bacterial colonies on each dish.
I.V. : Amount of antibiotic
D.V. : Number of colonies
