Answer: Third Option
-3, -1, 1
Step-by-step explanation:
By definition, the zeros of a function f(x) are all the values x for which f(x) = 0.
In other words, the zeros of a function f(x) are the intersections of the graph of f(x) with the axis of x.
Therefore, to identify the zeros of the function shown, identify the values of x in which the graph intersects the horizontal axis.
You can see in the graph that these intersections occur in
Finally the zeros are: -3, -1, 1

Answer:
x -5y = -20
Step-by-step explanation:
One way to write the equation for a line through two points is to use the slope formula. The slope is the same everywhere on a line, so the slope between the given points is the same as the slope between one of them and the general (x, y) point.
m = (y2 -y1)/(x2 -x1)
m = (5 -3)/(5 -(-5)) = (y -3)/(x -(-5))
2/10 = (y -3)/(x +5)
x +5 = 5(y -3) . . . . . . . multiply by 5(x+5)
x -5y = -20 . . . . . . rearranged to standard form
