Y=-1/5x+3 the 3 would be the y intercept and the -1/5 is your slope and you would start at the 3 and use your slope and go down one and over five since it’s negative
The answer to number 5 is 128
Answer: OPTION D.
Step-by-step explanation:
The vertex form of a quadratic function is:

Where (h, k) is the vertex of the parabola and "a" is the coefficient of the squared in the parabola's equation.
We know that the vertex of this parabola is at (5,5) and we also know that when the x-value is 6, the y-value is -1.
Then we can substitute values into
and solve for "a". This is:
