20 points

1. enter the equation in standard form. y – 7 = -(x + 4)

2. use the information given to enter an equation in standard form.
the points (8, 9) and (7, 6) are on the line.

3. identify whether each equation is in point slope form, standard form, or slope intercept form.
9x + 2y = 4
y – 8 = 2(x – 4)
y = 5x + 2
2x – 7y = -3

4. enter an equation in standard from to model the linear situation.
a bathtub that holds 44 gallons of water contains 19 gallons of water. you begin filing it, and after 5 minutes, the tub is full.

5. use the information given to enter an equation in standard form.
slope is 6, and the point (3, 8) is on the line.
