If you do a check (plug in your answer to y) that would be your reason
Answer:
Done below!
Step-by-step explanation:
(x - root)
(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

Answer:
y = -x + 4
Step-by-step explanation:
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = -1; y₁ = 5; m = -1 Substitute the values
y – 5 = -1(x + 1) Remove parentheses
y – 5 = -x - 1 Add 5 to each side
y = -x + 4
The graph is a straight line with a y-intercept at y = +4 and a slope = -10/10
= -1.
You need to select two points on the line:
The rise is the vertical distance, and the run is the horizontal distance:
Rise: Use the coordinates in y to find the rise:

Run: Use the coordinates in x to find the run:

The slope (m) is: 1/2 or 0.5
