Unit 2 Lesson 12

1. Plot a point to represent the y-intercept (b)

2. Use the slope to plot another point. (m)

3. Connect the dots.

​

​Graph Systems of Equations

y= 3/5x + 2
y= 1/5x + 4

​A stack of n small cups has a height, ℎ, in centimeters of h = 1.5n + 6


A stack of n large cups has a height, ℎ, in centimeters of h = 1.5n + 9

​

12.3: Stacks of Cups

Here is a graph that represents the equation for stacking the small cups and an equations for stacking the large cups. Use this to answer the next question.

​

12.3: Stacks of Cups

On the next slide is three systems of equations graphed on a coordinate plane

• You will match each figure to one of the systems of equations shown.

On the next slide you will find the solution to the system of equation.
