Question

Can someone please help me with this question? I don't know the formula or how to find it.

Answer 1

this is the question. I have to do number 4 only.

Answer 2

(-2,3).....x = -2 and y = 3
slope(m) = -2

y = mx + b
3 = -2(-2) + b
3 = 4 + b
3 - 4 = b
-1 = b

so your equation is : y = -2x + (-1)...or y = -2x - 1

Answer 3

oh..wait....point slope...hold on

Answer 4

y - y1 = m(x - x1)
(-2,3)....x1 = -2 and y1 = 3
slope(m) = -2
now we sub
y - 3 = -2(x - (-2) =
y - 3 = -2(x + 2)

Answer 5

point slope formula is : y - y1 = m(x - x1)
