Question

What is the slope and y-intercept of this line?

y = –3x + 9

Answer 1

What do you think?

Answer 2

I tried to find the slope and I got 3, but I don't do slope very well :(

Answer 3

do you know what form this equation is in?

Answer 4

Is it in slope intercept, standard form, or point slope form?

Answer 5

Slope intercept

Answer 6

what is Slope int form? y=mx+b?

Answer 7

I believe so

Answer 8

What do you think the m stands for in slope intercept form?

Answer 9

m, x and b have meanings.

Answer 10

I don't know, that's mainly what I don't understand. I'm homeschooled, so I don't have a very smart teacher online.

Answer 11

okay.

Answer 12

y=mx+b is my favorite form of an equation.

Answer 13

b=y-intercept in all y=mx+b equations

Answer 14

If you ever run into an equation with no b, then the y intercept is 0 (this only applies to Slope int form equations)

Answer 15

isn't it ax+by=c? or no

Answer 16

ax=by=c is standard form.

Answer 17

oh,

Answer 18

y = –3x + 9 Okay, back to this.

Answer 19

y=-3x+9 **
