Answer 1

you sure mi amigo?

Answer 2

To find the initial value (or y-intercept), you can use the point-slope form of a linear equation, which is y - y1 = m(x - x1). Plugging in the values m = -4/7, x1 = 14, and y1 = 3, we get:

y - 3 = -4/7(x - 14)

Now, let's simplify the equation:

y - 3 = -4/7x + 8

Next, let's isolate y by adding 3 to both sides:

y = -4/7x + 11

Therefore, the initial value or y-intercept of the linear function is 11. So, the correct option is:

b = 11

Answer 3

I apologize for the previous incorrect response. Let's calculate the correct initial value:

We know that the equation of the linear function can be represented as y = mx + b, where m is the rate of change and b is the initial value.

Given that m = -4/7 and the point (14,3) lies on the line, we can substitute these values into the equation to solve for b:

3 = (-4/7)(14) + b

3 = -8 + b

To solve for b, we can add 8 to both sides:

b = 3 + 8 = 11

Therefore, the initial value of the linear function is b = 11. I apologize for the confusion caused by the previous response.
