Question

Write an equation of a line in point slope form that has a slope of -3 and passes through the point
(3, -4).

Answer 1

\[Poin-Slope \space Form = y - y_1 = m(x - x_1)\]where m = slope and \((x_1, y_1)\)

Answer 2

I dont understand slope intercept at all

Answer 3

THis isn't slope-intercept though...

Answer 4

Its slope something

Answer 5

Just plug the numbers in...
m = -3
\(x_1\) = 3
\(y_1\) = -4

Answer 6

Is that seriously all I had to do? Why couldnt the teacher of just said that?!?!

Answer 7

You just have to know where the numbers come from.

Answer 8

So if thats how you do that. How do you do this?
Write the equation of a line in slope intercept form that passes through (2, 4) and (5, 4).

Answer 9

You have to first find the slope. Do you know the formula to find it?

Answer 10

y=mx+b?

Answer 11

THat's the form for slope-intercept. That comes later. The slope formula is:
\[m = \frac{y_1 - y_2}{x_1 - x_2}\]

Answer 12

So, you have two coordinates.
(2, 4) and (5, 4)
Now, let's say that (2, 4) is \((x_1, y_1)\). Does it make sense so far? That would make \(x_1 = 2\) and \(y_1 = 4\)

Answer 13

Could you tell me what \(x_2\) and \(y_2\) are?

Answer 14

2 and 4?
