Linear Functions Review

The line y = 4 is...

• Horizontal

• Vertical

The line x = -3 is...

• Horizontal

• Vertical

Coach Castillo gave his Algebra 1 the following assignment. Determine the x-intercept, y-intercept, slope and zero of the function graphed.

Which student answered correctly?

Identify the slope-intercept equation for the line graphed.

What type of slope does the graph have?

• Zero
• Undefined
• Negative
• Positive

What kind of slope would this line have?

• positive 
• negative 
• zero 
• undefined 

Write in slope intercept form
5x - 3y = -9

• y = (5/3)x - 3
• y = (5/3)x + 9
• y = (5/3)x + 3
• y = (3/5)x + 3

Which represents  -2x - 3y = 12 in slope intercept form.

Identify the x-intercept of the following linear equation written in standard form.

-8x - 4y = 8

• (-1, 0)

• (0, -1)

• (-2, 0)

• (0, -2)
