Interpreting Slope Intercept Graphs

The graph represents the height of a burning candle.  What is the meaning of the y-intercept?

• the time it takes to burn the entire candle

• the rate at which the candle is losing height

• the change in the height of the candle each hour

• the original height of the candle

What does the slope represent in this situation?

• The sloth runs 1 feet in 3 minutes

• The sloth runs 3 feet in 1 minute

• The sloth runs fast

• The sloth runs 6 feet in 1 minute

What does the y-intercept represent?

• The amount of each deposit made

• The initial amount of money in the savings account

• The number of deposits made

• The amount of money in the savings account after 50 deposits

What is the slope in this equation:

y = 2x + 3

• 2

• 3

• 5

• Cannot be Determined

What is the y-intercept in the equation y= -2x + 5

• -2

• 3

• 5

• Cannot be Determined

What is the equation of this line?

• y = 2x + 2

• y = 2x - 2

• y = - x + 2

• Cannot be Determined

Write an equation that represents the graph in slope-intercept form.

• y = 2x + 7

• y = - 3x - 5

• y = 2x - 1

• y = - 2x + 6

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

• y = - 1x + 3

• y = - 4x + 3

• y = 1/4x + 3

• y = 4x + 3

Find the slope

• -5/7

• 7/5

• -7/5

• 5/7

Which is FALSE about the line y=3x+7

• The slope is 3/1

• The x-intercept is 3

• The y-intercept is 7

• The line goes up from left to right
