Linear Functions

Write the equation for the line in slope-intercept form.

• y= -1x+3
• y= 4x+3
• y=1/4x+3
• y= -4x+3

Write the slope intercept form of the equation graphed.

• y = -2x + 3
• y = 1.5x + 2
• y = 2x - 3
• y = -1.5x - 2

Write a linear equation in slope intercept form of a line with a slope of -3 and y intercept of 0

• y=-3
• y=3x
• y=-3x
• x=-3

Are these two lines parallel, perpendicular or neither?

y = -1/4 x - 5

y = 4x + 2

• Parallel

• Perpendicular

• Neither

Are these two lines parallel, perpendicular or neither?
y = -1/3x - 5
y = 1/3x + 2

• Neither

The slopes of parallel lines are...

• the same

• opposite

• always different

True or false:
The x-intercept of a function ALWAYS occurs where y is equal to zero.
