Question

Given the following two points on a line, write the equation of the line in slope-intercept and point-slope form. (1, 4) and (-3, -2)

Answer 1

We have to find slope first use slope = y2-y1/x2-x1

Answer 2

so then 3 and 1

Answer 3

No the slope will be 1.5

Answer 4

Here compare ( x1 , y1 ) and ( 1 , 4 ) so x1 = --- ? y1 = --- ?

Answer 5

y=1.5x+2.5

Answer 6

That's the slope intercept form...

Answer 7

Now do the point-slope form.

Answer 8

Okay would the point-slope be y= 3x/2 + 5/2

Answer 9

y-4=1.5x (x-1)

Answer 10

That's the point-slope form...

Answer 11

How did you get that? I'm not sure if that's right...

Answer 12

Oh okay

Answer 13

Yeah, your equation didn't work...it was half right. Good luck!
