@iGreen.

anonymous · Answer

First, we can find the y-intercept, that's the place where it intersects on the y-axis, and what's that?

anonymous · Answer

4

anonymous · Answer

Yes, so we have:

y = [_]x + 4

anonymous · Answer

Now for the slope, we can take any two points on the line and plug it into the slope formula.

anonymous · Answer

(0,4)?. . . or (5,0)

anonymous · Answer

We can use both.

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{0-4}{5-0}$

Simplify that

anonymous · Answer

-4 and 5

anonymous · Answer

Yep, so the slope is -4/5

So our final answer is:

y = -4/5x + 4

thank you

oh and @iGreen. its a creeper from minecraft. . . if thats what you ment by "and what's that?"

anonymous · Answer

No I meant the y-intercept when I said that.
