Linear Equation

Write a linear equation in slope-intercept form give the point and slope. (-6, -11); slope = 1/2 

Write an equation in slope-intercept form given the point and slope: (-4, -7); slope = 1

What is the equation and slope of the line shown on the grid?

• y = 6; slope is -1

• x = 6; slope is zero

• y = 6; slope is 6

• x = 6; slope is undefined

At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven. 

• y = x(35 + 0.75)
• y = 35x + 0.75
• y = 0.75x + 35
• y = 0.75(x + 35)

Is the graph linear, exponential or neither?

• Linear
• Exponential
• Neither

The start up cost to join eTunes music is $7.95 plus $0.95 per song downloaded.  Write a linear equation that could be used to find how many songs he downloaded.

• y = 0.95x + 7.95
• y = 7.95x + 0.95
• y = 0.95x - 7.95
• y = - 0.95x + 7.95

Convert the standard form equation into slope-intercept form.

6x - 7y = -35
