Calculating Slope from a Graph

Multiple Choice

Calculate the slope.

m=-4/3

m=4/3

m=-3/4

m=3/4

Multiple Choice

Multiple Choice

Find the slope

-2/3

3/2

-3/2

2/3

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

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
