Triangle DEF has vertices D ( -5, -1), and E (3,3), and F (-1,5). Fine the equation of the altitude through F in slope intercept form.

Question

how would you work this out?

next time, i can do it by myself :)

thank you!

Answer 1

Determine slope of line through DE

Make negative reciprocal for slope of line of altitude

Use point-slope form to determine equation.
