Constructing Liner Equations

Find the slope using these two points: (24,6) (4,2)

• 5

• -5

Find the equation using the table.

• y = 1/4x + 5

• y = 4x - 5

• y = -4x + 5

• y = -1/4x + 5

 

Bob has $150 in his savings account and saves $40 per month. Which equation represents the amount Bob has in his account after x months? 

• y =150x + 40

• y = 40x - 150

• y = 150x - 40

• y = 40x + 150

Construct a linear model for the graph.

• y = 1/2x - 2

• y = -1/2x - 2

• y = 2x - 2

• y = -2x - 2

Construct a linear model for the table.

• y = 8x + 2

• y = -6x + 2

• y = 6x + 2

• y = 6x + 8

A factory produces 25 cars each day.  There are already 20 that have been completed.  Construct a linear model to represent the number of cars in the factory.

• y = 20x + 25

• y = 25x − 20

• y = -25x + 20

• y = 25x + 20

The slope of a line is 5 and passes through the point (2, -3).

If you are trying to find the y-intercept, what variable will be replaced with the number 2 in y = mx + b ?

• x

• y

• m

• b

What is the rate of change for the given points?

(3, 8) and (5, 7)

A linear function will....

• ... have a constant rate of change and be a curved line

• ... not pass the vertical line test

• ... have a constant rate of change and be a straight line.

• ... graph as a curved line

Where do you find the initial value on a graph?

• Where the graph touches the y-axis (x=0).

• Where the graph touches the x-axis (y=0)
