@Ashleyisakitty
Can someone answer them it's only 2 questions...I really need help

hey how can i help u
can you help me answer the questions above?
the attachments
sure whats the question
they're above :)
anybody at all? these are the last 2 questions I have to answer in order to pass
the graph one is a
are you sure?
it's supposed to be more then one answer
the second one u posted not the first one
wait no sorry its D
sorry
give me a min ill explain it to u
ok...
look at where the line crosses the y axis
mhm
first one....find the slope by using the slope formula and the two sets of points on the line slope(m) = (y2 - y1) / (x2 - x1) (3,4)...x1 = 3 and y1 = 4 (-3,1)...x2 = -3 and y2 = 1 now we sub slope(m) = (1 - 4) / (-3-3) slope(m) = -3/-6 slope(m) = 1/2 now use y - y1 = m(x - x1) slope(m) = 1/2 (3,4)..x1 = 3 and y1 = 4 now we sub y - 4 = 1/2(x - 3) <=== here is one same thing using other points y - y1 = m(x - x1) slope(m) = 1/2 (-3,1)....x1 = -3 and y1 = 1 now we sub y - 1 = 1/2(x - (-3) y - 1 = 1/2(x + 3) <=== here is another one
cool what about the second one?
ok...lets see what I can do with it...give me a sec
slope(m) = (y2 - y1) / (x2 - x1) (0,1)...x1 = 0 and y1 = 1 (2,-2)...x2 = 2 and y2 = -2 now we sub slope(m) = (-2-1) / (2-0) slope(m) = -3/2 now use y - y1 = m(x - x1) slope(m) = -3/2 (0,1)...x1 = 0 and y1 = 1 y - 1 = -3/2(x - 0) y - y1 = m(x - x1) (2,-2)...x1 = 2 and y1 = -2 y - (-2) = -3/2(x - 2) y + 2 = -3/2(x - 2) hmmm...not getting your answer choices let me try something y + 2 = -3/2(x - 2) y + 2 = -3/2x + 3 y = -3/2x + 3 - 2 y = -3/2x + 1 y - 4 = -3/2(x + 2) y - 4 = -3/2x - 3 y = -3/2x - 3 + 4 y = -3/2x + 1 ok....its gonna be y - 4 = -3/2(x + 2)
I see what I did...I should have used the points (-2,4) and I would have gotten to the answer a whole lot easier
you sure?? final answer?
positive
ok thanks I got %100
sweet :) I love to hear that
do you think you could help me with something else?
