Creating Equations

In either a Table or Graph, you must find the slope (m) and the Y-Intercept (b) and substitute those values into the formula y = mx + b

Multiple Choice

Which equation matches the graph? (Click me to see the image)

• y = 2x
• y = 1/4 x + 2
• y = 1x + 4
• y = -2x

Multiple Choice

Write the equation of the line.

• y= -1x-3
• y= -3x-1
• y=-1/3x-1
• y= -3x-3

Multiple Choice

What is the function of the table?

• y=3x+1
• y=4x-2
• y=x+1
• y=x+7

Multiple Choice

Which equation matches the table?

• y = x 
• y = 5x
• y = x - 4
• y = x + 4

Proportional & N/Proportional Relationships

Proportional & N/Proportional Relationships

• A Table is proportional if the Ratios are equivalent & it passes through the Origin (0,0).

• A graph is proportional if it is Linear and it passes through the origin.

• An Equation is proportion if it only has a slope and the Y-Intercept is 0.

Multiple Choice

Which relationship is an example of a proportional function?

• a rental company charges $80 per day and a one-time fee of $24
• a taxi ride costs $2 for the first mile and $4 for each additional mile
• a gym membership cost $30 per month and an additional annual registration fee of $75
• Beverly earns $210 a week for 4 weeks

Multiple Choice

REVIEW QUESTION

• Proportional
• Non-Proportional

Multiple Choice

Which graph is proportional?

• A
• B
• C and D
• All of the graphs are proportional

Multiple Choice

REVIEW QUESTION
Which best describes the graph represented in this table?

•  proportional
• non-proportional

Multiple Choice

Does this graph represent a proportional relationship?  

• No, because it doesn't pass through the origin.
• Yes, because it doesn't pass through the origin.
• Yes, because it intersects the y axis.
• No, because it intersects the x axis.
