Answer 1

ok give em to me

Answer 2

???

It says 'Which equations are equations for the line shown?'.

That doesn't make any sense.

Answer 3

Oh, nevermind..it's asking what equations match the line?

Answer 4

Well first we can find the slope. It already gives us (-3, 1) and (3, 4).

Plug them in the formula:

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

\(m = \dfrac{4-1}{3+3}\)

Add & Subtract:

\(m = \dfrac{3}{6}\)

Divide:

\(m = 0.5~or~\dfrac{1}{2}\)

Answer 5

Do you know what the y-intercept of the line is? @LOLAri

Answer 6

The y-intercept is where the line crosses at the y-axis.

Answer 7

So the y-intercept here is..?

Answer 8

A. y-3=-1/2(x-4)
B. y-4= 1/2(x-3)
C.y-3= 1/2(x+1)
D. 4-1= 1/2(x+3)

Answer 9

Oh, I already told you that the slope was 1/2.

Those equations are in the form of:

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

Where \(y_1\) is the y-value.
Where \(x_1\) is the x-value.
Where \(m\) is the slope.

They gave you two points:

(-3, 1) and (3, 4)

They're both in the form of (x-value, y-value)

And the slope is 1/2, so what's your answer gonna be? @LOL
