Which graph represents the function y = 2x – 4? A coordinate plane with a line passing through (negative 4, 0) and (0, 2). A coo
VARVARA [1.3K]

Answer:

The third option: "A coordinate plane with a line passing through (0, negative 4) and (2, 0)."

Step-by-step explanation:

Use the equation defined by the function: y = 2x - 4 to check the (x, y) values they give you. If they both render true mathematical statements, those are indeed points on the plane that belong to the given line.

For the third case; the pairs (0,-4) and (2,0), both satisfy the equation of the line that is given.

For (0,-4):  y = 2x - 4 becomes:

(-4)=2(0)-4\\-4=0-4\\-4=-4 which is a TRUE statement

For (2,0):  y = 2x - 4 becomes:

(0)=2(2)-4\\0=4-4\\0=0 which is also a TRUE statement.

This option is the only one that verifies both given points as truly being part of the given line.

Tonya is twice Kevin's age. In three years, Tonya will be 17. And in another three years, Uncle Rob will be three times Tonya's
Nady [450]

Step-by-step explanation:

"In three years, Tonya will be 17."

14 + 3 = 17, so Tonya is 14 atm. (At The Moment)

"Tonya is twice Kevin's age." Kevin is 7, because 7 x 2 = 14.

"In another three years, Uncle Rob will be three times Tonya's age."

Since Tonya is 14, multiply 14 x 3 and you get 42.

If you're asking for the three years, 17 x 3 = 51 < Uncle Rob's age

Kevin is about 8 1/2 years old. Since 8 x 2 = 16, I multiplied 8 1/2 x 2 and got 17.

I hope this helped.
