Different Types of Slopes

How would you write the equation with a slope of 2/3 and a y-intercept of -3

• y=3/2x+3

• y=2/3-3

• y=2/3x-3

• y=2/3x+3

Given the equations, below what type of lines are formed? Why?

• a. Straight Lines

  because it is in the form:

  y = mx + b

• b. Intersecting Lines

  Different slope and different

  y-intercept

• c. Same Line

  same slope and same y-intercept when the 2nd equation is divided by 2.

• d. Parallel lines

  Same slope and Different y-intercept

Match the slopes and y-intercepts that would create this type of graph.

• DIFFERENT slopes
  

• SAME slopes but DIFFERENT y-intercepts
  

• SAME slopes and SAME y-intercepts

Match the slopes and y-intercepts that would create this type of graph.

True or False: Line LP has the same slope as Line LM

• True, slope is constant

• False, slope is not constant

True or False: Triangle A and Triangle B show different slopes.

• False, both slopes equal 0.25

• True, 2/8 is different than 1/4
