Answer:

C. -2

Step-by-step explanation:

You have to look at the factor in front of the x after normalizing the equation in to y = ax + b. In other words, find a.

y+2 = -2(x-3) =>

y = -2x + 6 - 2

y = -2x + 4

a = -2

b = 4

Answer:

C. -2

Step-by-step explanation:

  • y+2=−2(x−3)

Bringing the equation to slope-intercept form of y = mx + b, where m is a slope:

  • y + 2 = - 2x + 6
  • y = -2x + 6 -2
  • y = -2x + 4
  • As m = -2, the slope is -2

Correct answer choice: C. -2
