Convert this equation into slope-intercept form: 3x + y = 12
Convert this equation into slope-intercept form. x + y = 4
Solve this equation for y:
10x −5y=30
y = 2x - 6
y = -2x + 6
y = -10x + 30
y = 10x - 30
4x - 5y = 40

5. Which of the following pair of points have a slope of -2?
(2, 4) and (5, - 2)
(4, 2) and (- 2, 5)
(2, 5) and (4, - 2)
(- 2, 2) and (4, 5)
7. What is the equation of a line that passes through the points (0, 5) and (2, 2)?
𝑦 = - 3⁄2 𝑥 + 5
𝑦 = - 2⁄3 𝑥 + 5
𝑦 = 2⁄3 𝑥 + 5
𝑦 = 3⁄2 𝑥 + 5
8. The line passes through the point (0, 3) and has a slope of 2. What is the equation of a line in slope-intercept form?
𝑦 = 2⁄3 𝑥
𝑦 = 2⁄3 𝑥 + 3
𝑦 = 2𝑥 + 3
𝑦 = 3𝑥 + 2
10. Jojo was able to collect 5 kg of aluminum cans of soft drinks and sold them to the junk shop and received $175. On the next day, he sold again another 3 kg of recycled cans and earned $105. He wanted to know how much would he earn from the recycled materials if he collected 22 kg.
What equation would he have used to determine his earnings?
y = 5x
y = 5x + 35
y = 35x
y = 35x + 5
A music app charges $2 to download the app plus $1.29 per song downloaded. Write a linear equation to find the total cost to download any number of songs.
y = 1.29x + 2
y = 1.29 + 2x
30 = 1.29x + 2
y = 1.29 x - 2
The start up cost to join eTunes music is $7.95 plus $0.95 per song downloaded. If Jill spent $26, write and solve a linear equation to find how many songs she downloaded.
