Question

The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD?

Answer 1

Do you know the formula for perpendicular slopes?

Answer 2

$$\huge m_1*m_2=-1$$

Answer 3

It says like 1/2 and 2 and -1/2 and -2 as the answer

Answer 4

What is the slope of line CD?

Answer 5

The equation of line CD is (y−3) = − 2 (x − 4). It says that

Answer 6

So from that tell me what its slope is please.

Answer 7

Idk how to do this

Answer 8

This equation (y−3) = − 2 (x − 4) is in what is called the point-slope form: $$y-y_0=m(x-x_0)$$ Have you seen this form before?

Answer 9

No

Answer 10

m is the slope of this line, please tell what m is equal to.

Answer 11

-2?
