Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-15=\dfrac{6-15}{1-(-2)}(x-(-2))

y-15=\dfrac{-9}{1+2}(x+2)

y-15=\dfrac{-9}{3}(x+2)

y-15=-3(x+2)

Adding 15 on both sides, we get

y=-3x-6+15

y=-3x+9

Putting x=0, we get

y=-3(0)+9

y=0+9

y=9

The y-intercept is 9. Therefore, the correct option is C.

Ratling [72]
Since, she has already been working for two hours (120 minutes) and has budgeted only 6 hours (360 minutes) to create the centerpieces.

Since, each centerpiece takes 15 minutes to make, the time it takes her to make x centerpieces is given by 15x.

Therefore, the correct inequality representing the situation is given by 120 + 15x <span>≤ 360.</span>
