8th U4L11 On Both of the Lines

Write the equation of the line.

• y = -1/3x + 2

• y = 1/3x - 2

• y = 3x + 2

• y = -3x - 2

Write an equation for the line shown by counting the slope and identifying the y-intercept.

• y = -2x + 4

• y = 2x + 2

• y = 1/2x - 2

• y = -1/2x + 2

Write the y=mx+b equation for the following line.

• y = 2/3x - 1.5

• y = 2x + 3

• y=3/2x + 2

• y = 3x + 2

Drag the points to graph the line y = 1/2x + 3

Remember this means: y-intercept is 3 and rise/run slope = 1/2 meaning rise 1 and run right 2.

Draw the two points to make the equation for the following situation:

You start with $12 and then you save $2 each day!

The graph on the right shows Devin walking at a speed of 2 meters per second.

Joe is starting at a distance away from Devin and is walking TOWARDS them at a speed of 3 meters per second.

If Joe and Devin meet at (2,4), where is the point where Joe started?

Randy is outside looking for their dog. The graph shows them starting at home and walking at a rate of 1/2 meters per second.

Their dog, Roxy, was lost but smells Randy and starts running toward them at a rate of 4 meters per second. Roxy meets Randy at the point (2,1) Plot the starting point for the dog, Roxy.
