Equations and Their Graphs

Consider the equation:
y=-x+4
Identify the slope and
 y-intercept.

• m=4, b=-x
• m=-x, b=4
• m=1, b=4
• m=-1, b=4

Which line has a
positive slope?

• Blue
• Red
• Purple
• Green

What is the slope of this line?

• m = 0

• m = undefined

• m = 3

• m = ¹/₃

What is the slope of this line?

• m = 0

• m = undefined

• m = 5

• m = ¹/5

Determine the slope between
 (4,2) and (-3,5).

• 3/1
• -7/3
• 3/7
• -3/7

What is the y-intercept

• (2,0)
• (0,2)
• (0,-2)
• there is no y-intercept

Write the equation in slope intercept form.

5x + y = -5

• y = -5x - 5

• y = ⅕x - 5

• x = 5x - 5

• y = 5x - 5

Write the equation of the line.

• y = -1/3x - 2
• y = 1/3x - 2
• y = 3x - 2
• y = -3x - 2

Write the equation of the line.

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