Graphs of Linear Functions in Slope-Intercept Form

Find the slope

• -5/3
• -3/5
• 5/3
• 3/5

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2
• -1/2
• 2
• -2

y = -x - 3

SLOPE is

• 3

• 1

• -1

• -3

Answer explanation

Slope is always a coefficient of x.

y = -x - 3

Y-intercept is

• 3

• 1

• -1

• -3

Answer explanation

Y-intercept is always a constant.

When graphing, one always marks FIRST

• the y-intercept on the y-axis

• the slope on the y-axis

• the y-intercept on the x-axis

• the slope on the x-axis

Find the slope-intercept equation

• y = 3x + 5

• y = -3x + 5

• y = ^-1/₃ x + 5

• y = ^-1/₃ x - 5

Find the slope-intercept equation

• y = 4x + 6

• y = -4x - 6

• y = 1/4x - 6

• y = -1/4x + 6

Which is the graph of y= -x + 2? 

• A
• B
• C
• D
