1. A theater is designed with 12 seats in the first row, 18 in the second row, 24 in the third row and so on. If this seating pattern continues, how many seats are the 20th row?
2. Rewrite the equation 8x + 4y = 16 in slope-intercept form.
3. Rewrite the equation 20x - 5y = 30 in slope-intercept form.

1. 126

2. y = -2x + 4

3. y = 4x - 6

Step-by-step explanation:

1. 12 + 6 * 19 = 126

2. 8x + 4y = 16

   (4y = -8x + 16) / 4

    y = -2x + 4

3. 20x - 5y = 30

   (-5y = -20x + 30) / -5

    y = 4x - 6
