use the image to answer the question. the image shows a line going from around (2.5,5) to around (3.5,5) there is 3 plotted points. they are (0,0) (0.5,1) and (-1.5, -3)

Question

determine the initial value and the rate of change of the linear function as given in the graph.
A: the initial value is -6 and the rate of change is 2
B: the initial value is 2 and the rate of change is 2
C: the initial value is 0 and the rate of change is 2
D: the initial value is 0 and the rate of change is 1/2

Answer 1

To determine the initial value and rate of change of the linear function, we need to find the equation of the line passing through the two given points (2.5, 5) and (3.5, 5).

The formula for the equation of a linear function is y = mx + b, where m is the rate of change (slope) and b is the initial value (y-intercept).

Using the formula, we can find the slope (rate of change):
m = (y2 - y1) / (x2 - x1)
m = (5 - 5) / (3.5 - 2.5)
m = 0 / 1
m = 0

Since the slope (rate of change) is 0, the options that have a rate of change of 2 are not correct.

Now let's find the initial value (y-intercept) by substituting one of the given points into the equation:

Using the point (0.5, 1):
1 = 0(0.5) + b
1 = b

Therefore, the initial value (y-intercept) is 1.

The correct answer is:

C: The initial value is 0 and the rate of change is 2.

Answer 2

bot. you got me a 3/5 thats not good.

Answer 3

I apologize for the mistake. Let's reevaluate the problem. Since the line passes through the points (2.5, 5) and (3.5, 5), we can calculate the rate of change (slope) using the formula:

m = (y2 - y1) / (x2 - x1)
m = (5 - 5) / (3.5 - 2.5)
m = 0 / 1
m = 0

The rate of change is indeed 0, not 2 as mentioned in my previous response.

Now let's determine the initial value (y-intercept) by substituting the coordinates of one of the given points into the equation:

Using the point (0.5, 1):
1 = 0(0.5) + b
1 = b

Therefore, the correct answer is:

D: The initial value is 0, and the rate of change is 1/2.
