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

Linda bought a Bloodgood Japanese Maple tree. In two years, the tree was 7' tall and in 10 years the tree grew to its mature height of 15'. Write an equation in slope-intercept form that shows the number of years, t, it takes to reach a certain height, h.

• h = - t + 9

• h = t + 5

• h = t - 9

• h = -t + 5
