Suppose we start with a value of x 59 a What expression rep

Suppose we start with a value of x = -5.9 a. What expression represents the change in x from x = -5.9 to any possible value of x ? Preview b. Suppose a linear relationship exists between y and x and the change in y is always -4 times as large as the change in x . What expression represents the change in y from x =-5.9 to any possible value of x ? Preview

Solution

x is the new value
The original value was x = -5.9

So, change in x from original to new =
new - original
x - (-5.9)
x + 5.9 ------> ANSWER

------------------------------------------------------------------------

Change in y is always -4 times as large as change in x
So, slope = -4

And the equation is :

delta(y) = -4(x + 5.9)

OR

delta(y) = -4x - 23.6 ----> ANSWER

-------------------------------------------------------------------------

x is the varying value of quantity A
y is the varying value of quantity B

Definitely not the first two options as we cannot have y on one side and change in x (dektax) on the other side....

Options 4 and 5 are the answers.
When we rewrite 4, we anyways get 5.
So, both options 4 and 5 are the answers
