Question

An equation of the line that passes through the point (0,-1) and whose slope is 2 is

A) y=2x+2 B) y=-2x-1 C) y=-x+2 D) y=2x-1

Answer 1

A. y=2x+2

Answer 2

thx

Answer 3

its not A

Answer 4

@hartnn why?

Answer 5

\(y-y_1 = m(x-x_1)\)

m = 2
x1 = 0, y1 = -1
plug in the values, what u get ?

Answer 6

y-(-1)=2(x-0)

Answer 7

yess
so,
y+1 = 2x
subtracting 1 from both sides will give you your answer :)

Answer 8

It's either B or D

Answer 9

is it D?

Answer 10
