5) Without graphing, answer the following for each equation.
• Looking from left to right, does the line slope UP or DOWN?
• Is the line STEEPER or FLATTER than the parent graph y = x?
• What is the y-intercept.
STEEPER or FLATTER
Equation
Slopes UP or DOWN
y-intercept
than parent graph y = x
y = 3x - 4
y = -2x + 1
y =
x - 5
y = -6x + 11
y = -
x - 10
y = 0.1x - 9
y = -1.3x + 4
y =
x
y = x + 2
y = - x - 1
