Answer:
No
Step-by-step explanation:
In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4. This means it is not a function, but it is paired with two different values.
Answer:
(1,-2)
Step-by-step explanation:
The solution is (1,-2) because that's where the the lines cross over each other. The x in the equation is what you move by, remember rise over run. The second number is your starting point, so -3 and positive 3 in this case.
The answer would be y = 2 over 3x - 4
The answer would be 266400. If you would convert hrs into seconds.
Replace x with the x values of the choices and see if it solves to equal the y value:
Y=-7x + 2
A) (1,2)
Y = -7(1) + 2 = -7 + 2 = -5 not 2
A is wrong
B (8,-54)
Y = -7(8) + 2 = -56+ 2 = -54
This works out.
The answer is B
