goldenfox [79]

Answer:

  • C is the correct one

Step-by-step explanation:

<h3>Given</h3>

<u>Function </u>

  • y = -3/2x - 2
<h3>To find </h3>
  • The correct graph
<h3>Solution</h3>

We can see all 3 graphs have y-intercept of -2

Since the slope is negative, it is decreasing function, therefore possible options are A or C

<u>Checking x-intercept and comparing with same of A and C</u>

  • y = 0
  • -3/2x - 2 = 0
  • -3/2x = 2
  • x = -4/3 = -1.33

As we see it matches Option C, which is the answer
