Question

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope of −3.

Answer 1

ill give you an example, and see if you get it:

Answer 2

alright thank you.

Answer 3

* Find the equation of the straight line that has slope m = 4 and passes through
the point (–1, –6).
They've given me m = 4, x1 = –1, and y1 = –6. I'll plug these values into the point-slope form, and solve for "y=":

y – y1 = m(x – x1)
y – (–6) = (4)(x – (–1))
y + 6 = 4(x + 1)
y + 6 = 4x + 4
y = 4x + 4 – 6

y = 4x – 2 Cop

Answer 4

this is called the point slope formula
y – y1 = m(x – x1)

Answer 5

please add as fan :DD

Answer 6

im going to try to figure it out right now. please tell me if i get the right answer.

Answer 7

yes, i will

Answer 8

oh, ignore the "cop" in the end. that not part of it

Answer 9

y-6=-3(x-(-1)
y+6=-3(x+1)
y+6=3x+1
y=3x+4+1
y=3x+5

Answer 10

wait is it y=-3x+3?

Answer 11

ok, so you knew what you were doing, but you messed up on the second line. you dont make -6, to +6. They did that, because it was already a negative, so it becomes a positive( y-(-3) become y+3

Answer 12

your second answer is right

Answer 13

okay thank you! :)

can you help me with giving me some more examples to other problems that i give you?

Answer 14

sure, but i gtg , in a sec

Answer 15

alright, just tell me when your back on.
