Answer:
A constant is a number that stays the same. A variable is number that doesn't remain the same.
Your fraction answer would be I think 1/15
The slope of (1,-3) and (2,2) is 5
The zeros of a function are the values of x that make the function be equal to zero.
When graphing a quadratic equation, the graph is a parabola, and the zeros of the function are the x-intercepts of the graph, which are the points where the graph intersects the x-axis.
So, if the zeros of this function are x = -8 and x = 2, that means the parabola crosses the x-axis at x = -8 and x = 2.
Therefore the correct option is the first one.
