Question

If the slope of a straight line is 0 and the y-intercept is –2, what is the equation of the line?

Answer 1

y=mx+b
m=slope
b=y-intercept

Answer 2

y=2x??

Answer 3

\(\sf\Large y=\color{red}{m}x+\color{blue}{b}\)

\(\sf\Large\color{red}{m}=slope\)
\(\sf\Large\color{blue}{b}=y-intercept\)

Answer 4

y = x-2 ?

Answer 5

You were given

\(\sf\Large\color{red}{m}=slope=0\)
\(\sf\Large\color{blue}{b}=y-intercept=-2\)

Answer 6

It's a simple plug in...

Answer 7

Making a sketch may help :)

Answer 8

it's not simple to me, actually.

Answer 9

What do all horizontal lines have in common?

Answer 10

They have the general form: y = c.

Answer 11

Where c stands for a constant.

Answer 12

In this case that constant is the y-intercept.
