Question

question 7 of 10
what is the slope of the line described by the equation below?
y - 9 = -2(x - 8)

a. 2
b. 9
c. -2
d. -9

Explanation:

Step1: Recall point - slope form

The point - slope form of a line is given by \(y - y_1=m(x - x_1)\), where \(m\) is the slope of the line and \((x_1,y_1)\) is a point on the line.

Step2: Compare with given equation

We are given the equation \(y - 9=-2(x - 8)\). Comparing this with the point - slope form \(y - y_1=m(x - x_1)\), we can see that \(m=-2\).

Answer:

C. -2
