1) suppose y varies directly with x, and y=12 when x=-3, what is the value of y when x=6?

a) -24

b) 2

c) -2

d) -4

2) what is the equation of a line with a slop of -7 and a y-intercept of 6?

a) 6y = -7x

b) y = 6x + (-7)

c) -7y = x + 6

d) y = -7x + 6

3) what is the equation of the line through (5,1) with a slope of -3

a) y + 1 = 3(x + 5)

b) y - 1 = 3(x - 5)

c) y - 1 = -3(x - 5)

d) y + 1 = -3(x - 5)

4) what is the equation of the given line in point-slope form?

a) y - 1 = 2(x + 2)

b) y - 1 = 2(x - 2)

c) y - 2= 2(x - 1)

d) y - 2 = 1/2(x +2)
