Question

Find the value of y for which the line A & B has the given slope m: A(-2, 3), B(4,y), m=-2/3. Thanks

Answer 1

use the slope intercept form to define the line with the slope and A, then plug in x=4 to solve for the missing y

Answer 2

\[y=m(x-A_x)+A_y\]
\[B_y=m(4-A_x)+A_y\]

Answer 3

Okay thanks .

Answer 4

I got -1

Answer 5

another method is just to use the slope formula

A(-2, 3)
- B( 4 ,y )
----------
-6, 3-y

\[\frac{y-3}{6}=-\frac23\]

Answer 6

y-3=-4 when y=-1
