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

it is BA.

$$\huge slope = \dfrac{y_2-y_1} {x_2-x_1}$$

plug in the values for BA you will get,
$$\huge slope =\dfrac{0-2}{16-9}$$

$$\huge it\ is = -2/7$$

Answer 2

thank you, geometry is so hard for me

Answer 3

$$\huge \frak\color{red} {WELCOME..........}$$
