Question

What is the slope of the line described by the equation below?

y- 9 = -2(x- 8)
Α. 2
Β. -2
C. 9
D. -9

Answer 1

Option B

Explanation:

The equation is in point slope form.
`y-y_1=m(x-x_1)`

'm' - Slope

(x1,y1) - Coordinate

'-2' is in the place of 'm'. This means that '-2' is the slope of the line.

Option B should be the correct answer.

Answer 2

B. -2

y-9=-2(x-8)

y-9=-2x+16

y=-2x+25

The slope is -2

Hope this helps!
