Question

question 9
given the function $y = \frac{1}{2}x - 2$, which set of numbers completes the table?

x	y
-2
0

a {4, 3, 2}
b {-4, -3, -2}
c {-4, 3, 2}
d {4, 3, 2}

Explanation:

Step1: Substitute $x=-4$

$y = \frac{1}{2}(-4) - 2 = -2 - 2 = -4$

Step2: Substitute $x=-2$

$y = \frac{1}{2}(-2) - 2 = -1 - 2 = -3$

Step3: Substitute $x=0$

$y = \frac{1}{2}(0) - 2 = 0 - 2 = -2$

Answer:

B. {-4, -3, -2}
