Question

Determine an equation of the line with the given slope m that passes through point m=0, (-1,3)

Answer 1

Are you familiar with point slope formula? It makes doing this very easy

Answer 2

or you can use my favorite slope intercept form

Answer 3

I am very unsure of what forms to use with this one. I do know the formula when you have 2 sets of points.

Answer 4

But for point slope you need two points...

Answer 5

When you have a point, and a slope. Use point slope.

\[y-y_0 = m(x-x_0)\]
Where m in the slope, and \(x_0,y_0\) are the x and y of the point.

Answer 6

Try it for the one you have here.

Answer 7

y-3=0(x-(-1))

Answer 8

Yep. Now simplify.

Answer 9

You still worken on it?

Answer 10

It should be very easy since 0 times anything is 0.

Answer 11

y=0

Answer 12

Not quite.

Answer 13

y-3 = 0

Answer 14

So y = ?

Answer 15

Okay, that is what I have on my paper. The reason I just put 0, is because all the examples show y-3=0...........then they show y=0

Answer 16

No, y = 3

Answer 17

That is why it's so confusing. The book is really bad.

Answer 18

So the line you described would be horizontal and maintain a constant value of 3 for any value of x.

Answer 19

So I literally write the equation y-3=0 since it wants an equation; not just an answer. Does that sound right?

Answer 20

You do need to write an equation. y = 3 is an equation.

Answer 21

Oh wow.... I really do appreciate your help. You make it so easy but this book; oh my goodness.

Answer 22

You want your equation in the form of y = something

Answer 23

Where something has an x or a constant term, or both.

Answer 24

okay
Thank s alot
