Answer 3

undefined slope would mean that the line is vertical (ie x = (something) )
at the point (3/2, 2/3) the x part of that is 3/2
therefore the equation would be x = 3/2

Answer 4

do u know how would it look on a graph

Answer 5

can you help me with some more

Answer 6

sure :)

Answer 9

a line that has a slope of 1
means that every time x increases by 1, y increases by 1
so you can immediately eliminate A and C
because the line is going downwards which would have meant a negative slope
Then between B and D which do you think has that
every time x increases by 1, y increases by 1

Answer 10

b?

Answer 11

am i right?

Answer 12

hmm... take a look at it.
for graph B every time x goes over 1 y goes up 1/2
we are looking for every time x increases by 1, y increases by 1

Answer 13

d?

Answer 14

yep :)

Answer 15

What graph represents the line that passes through (–2, 1) and has a slope of –2?

Answer 16

y = -2x - 3

Answer 17

What graph represents the line that passes through (–2, –3) and has a slope of 2/3 ?

Answer 18

y = 2/3x - 5/3

Answer 19

thanx a lot :D
