Consider the equation y = -2x + 5. Create a table of five ordered pairs that satisfy the equation. What is the y-intercept of th

Tatiana [17]

Answer: option d.

Step-by-step explanation:

To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":

For $x=-2$

$y = -2(-2) + 5=9$

For $x=-1$

$y = -2(-1) + 5=7$

For $x=0$

$y = -2(0) + 5=5$

For $x=1$

$y = -2(1) + 5=3$

For $x=2$

$y = -2(2) + 5=1$

Then, you can make the table:

x -2 -1 0 1 2

y 9 7 5 3 1

To find the x-intercept, substitute $y=0$ into the function and solve for "x". Then:

$0 = -2x + 5\\\\x=\frac{-5}{-2}\\\\x=\frac{5}2}$

This is: ( $\frac{5}{2}$ , 0)

To find the y-intercept, substitute $x=0$ into the function and solve for "y". Then:

$y= -2(0) + 5\\\\y=5$

This is: (0,5)

Can somebody please help me ( picture above )

Mnenie [13.5K]

Answer:

D. A number of books and their cost that is not possible with either subscription.

Step-by-step explanation:

If you look at the 2 lines on the graph, you see that the blue line represents the first subscription which charges a 96 dollar annual fee, and the red line represents the other subscription which charges 3 dollars per book.

Every point along these lines shows a price that could possibly be paid and a number of books that could be bought. The point where these two lines meet is where the amount of books borrowed and the price for those books is the same for both subscriptions.

Because point S is not at this intersection, nor is it on either of these lines, it is not possible to pay that price for that amount of books with either subscription.
