Question

Write the equation of the line that passes through 3,4 and 2,-1 in slope intercept form

Answer 1

Is this completely new, or have you forgotten how to do it, or is this for practice that you're just not sure of

Answer 2

I forgotten how to do this its been a long time

Answer 3

Okay, we first have to find the slope of this
Do you know the way to find that?

Answer 4

Where (x,y) (x,y)

Answer 5

So, we can get\[\frac{ 4-(-1) }{ 3-1 }\]

Answer 6

So, we have 5 as the slope

Answer 7

And now we have to find the y-intercept, we can do this by plugging in a coordinate, where y=mx+b, m is slope, b is y-intercept, so we have
(3,4) 5 as slope
4 = 3(5) + b
4= 15+b
b=-11

Answer 8

So, we have y=5x -11
