8th Grade Semester 1 Study Guide 1-12

1. What is the unit rate?

• 
• 10/5simplifies to 52 dollars every 1 ticket so that makes your answer $2
• Caption: To find unit rate, you want to find slope and simplify it . Unit rate is the ratio of y/1x

2. Find the graph that has a slope of 12

3. Unit Rate:

• You are looking for slope
• 

Find the Rate of change

• 
• remember that slope is y2-y1/x2-x1

5. Rate of Change

• 
• You need to find the slope from the table of values

6. Find the slope and y-intercept

• 
• count rise/run for slope and look for the point where your line crosses the y-axis for the intercept

7. multiple representations

• 
• Match the points in the table with the points on the line.

8. Multiple Representations

• 
• test the points in the equation against to see which table is correct.

9. multiple representations

• 
• match the intercept and the slope from the equation to the graph

10. Multiple representations

• 
• match the points in the table to the points on the line.

11. Direct Proportions

• 
• first find your constant: y/x
• Then plug it into the equations y=kx and solve for the missing variable.

12. Direct Proportion

• 
• find your constant: y/x
• Substitute your constant for k in the equation: y=kx and solve for the remaining variable.
