Answer:
D) y= 4x - 1
Step-by-step explanation:
We are basically trying to see which of the equations provided are true on both sides of the equal sign when you plug in the x and y values.
Let's start!
Choice A:
plug in 0 for x and -1 for y
-1 = 4(0)
And you are left with...
-1 = 0
This equation is false! Therefore it does not match the function in the table
Choice B:
plug in the values again
-1 = 0 + 1
-1 = 1
False!
Choice C:
-1 = 0 + 5
-1 = 5
False!
Lastly...Choice D:
-1 = 4(0) -1
Multiply 4 and 0 which is 0, so you are left with...
-1 = -1
This equation is true!!
So your answer is D
Hope this helps :D
Step-by-step explanation:
according to the drawing,
for x = 0 => y = 12
the coordinates of y-intercept : (0, 12)
so, y = f(0) = 12
The correct answer is 12 only
**CORRECTION** 21/2 because when you simplify it (dividing the top and the bottom by 2) you get 21/2. My first asnwer was a mixed number
