What's the y-intercept here?

The y-intercept is the place where the line crosses the y-axis.

anonymous · Answer

-6?

anonymous · Answer

Yep, you got it.

anonymous · Answer

Now we have to find the slope, we can take any two points on the line and plug them into the formula.

$m = \dfrac{y_2-y_1}{x_2-x_1}$

(0, -6) (6, 0)

$m = \dfrac{0+6}{6-0}$

Simplify that, tell me what you get.

anonymous · Answer

$$\frac{ 6 }{ 6} = 1$$

anonymous · Answer

Yep, so our final answer is:

$y = 1x - 6$

or

$y = x - 6$
