1. Find the slope of a line that passes through (-2 -3) and (1 1).

Question

a. 1/3
b. 1
c. 2
d. 4/2

2. For the equation -4y=8x, what is the constant of variation?
a. -4
b. -2
c. 1
d. 2

3. What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1)?
a. y=3x+1
b. y=x-3
c. y=2x+5
d. y=2x-5

Answer 1

I think B is -2

Answer 2

C is Y=2x-5

Answer 3

I think A is 1/3

Answer 4

Ok thanks Shalee :)

Answer 5

The first one was 4/3 but the other two were right thanks so much :)

Answer 6

oh :o

but yw

Answer 7

I just noticed I wrote 4/2 instead of 4/3 oops

Answer 8

1. slope = (1+3)/(1+2) = 4/3 , which is not in your list

2. -4y = 8x
y = -2x , so constant of variation is -2

3. d)
