For the function y=-1+6cos(2pi/7(x-5)) what is the minimum value?

The minimum value of y is -7

Step-by-step explanation:

Given:

We are given a cosine function.

We need to find minimum value of function.

Here y is depends on cosine function.

y is minimum when cosine is minimum because y is directly proportional to cosine function.

Minimum value of cos x is -1

Therefore, For minium value of y

Minimum value of y

Hence, The minimum value of y is -7

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
