Question

Slope of -7 includes point (3,p) and (2,2). What is the value of p?

Answer 1

p = - 5

Explanation:

(
`x_(1)` ,
`y_(1)` )

(
`x_(2)` ,
`y_(2)` )

m =
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`

~~~~~~~~~~~~~

( 3 , p )

( 2 , 2 )

m = - 7

`(2-p)/(2-3)` = - 7

2 - p = - 7 ( - 1 )

2 - p = 7

p = - 5
