k = - 7.5

Step-by-step explanation:

Slope "m" of a line through points

( , )

( , )

is m =

Slopes of perpendicular lines are opposite reciprocal: = - 1

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

The slope of a line through points (0, 7) and (2, 10)

= =

Slope of perpendicular line through points (3, 5) and (k, 12) is =

or =

=

2(k - 3) = - 21

k - 3 = - 10.5

k = - 7.5

if this is really you s much. i only have 3 points left and i have 2 questions to ask
