Question

I entered this function on Mathway.com, and had it graph the function.

y = -6x - 15

But for some reason, -6x becomes (1,-21). I have absolutely no clue how it converts like that. Could someone please explain?

Answer 1

What are you wanting to do with this? It's a pretty simple equation...

Answer 2

I just don't understand how to graph, I guess. I don't know what i'm doing wrong. I go down 15 for the Y value, and to the left twice for the X value.

Answer 3

I go left 6 times*

Answer 4

In the form y = mx + b, the m is the slope and the b is the y intercept. Stay with me here cuz this is really great to know.

Answer 5

I know slope intercept form

Answer 6

That is an ordered pair that fits the equation. No this is not how you graph. -15= the y-intercept so you got the first part right but second wrong.

Answer 7

I just don't know how to graph the X value

Answer 8

Your equation is y = -6x-15, so your 'b' is -15. That's where the graph goes through the y axis, like this:

Answer 9

Dude, I know that. I don't know where to put X.

Answer 10

Is there something I need to do to the coeffecient before I plot it?

Answer 11

I'm not a dude and I'm going to tell you where to put x.

Answer 12

just chill...

Answer 13

My apologies

Answer 14

Your slope is -6 so you go DOWN six units from your intercept and over to the right 1. Like this:

Answer 15

Ok

Answer 16

You don't need to draw it, lol
