Question

The vertices of a triangle are A(16, 0), B(9, 2), and C(0, 0).

Which side is also an altitude with a slope of -2/7?

Answer 1

ok , so u have 3 coordinate points, use the formula:\[slope = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\]
to get the slope for each line.
And then compare ur answer!

Answer 2

so you mean get the slope of A&B then B&C and C&A then compare?

Answer 3

yes!

Answer 4

line 1 = AB
line 2 = BC
line 3 = CA

Answer 5

A&B = -2/7
B&C = 9/2
C&A = 0/-16

Answer 6

so its A&B

Answer 7

tht is right!
