The answer is -1/4
Firstly you make a triangle on the line by plotting the points on where the line meets a point or coordinate.
Looking at the triangle, you will see that it goes up by 1 (the rise part) and it goes along by 4 (the run part)
rise/run = 1/4
The line is negative because if it went in the opposite direction, it would be positive, making the gradient or slope -1/4.
Sorry if that didn’t make sense
Answer:
The y- intercept could only be: B) (0, -3).
Step-by-step explanation:
The Y intercept is found when X=0, so the first value in the ordered pair must be 0. Because the line crosses the y axis BELOW the x axis, the value must be negative. Therefore, out of all the provided options, the answer could only be (0,-3).
Decimal form - 8.24
mixed number form - 8 1/4

The required poynomial equation is
.</h2>
Step-by-step explanation:
Given,
The zeros of the polynomial are - 4, - 2, 1 and 4
To find, the polynomial equation = ?
We know that,
The polynomial equation = (x - A)(x - B)(x - C)(x - D)
= (x + 4)(x + 2)(x - 1)(x - 4)
= [(x + 4)(x - 4)] [(x + 2)(x - 1)]
= (

)
= ![x^{4}+x^{3}-2x^{2}-16x^{2}-16x+32](https://tex.z-dn.net/?f=x%5E%7B4%7D%2Bx%5E%7B3%7D-2x%5E%7B2%7D-16x%5E%7B2%7D-16x%2B32)
= ![x^{4}+x^{3}-18x^{2}-16x+32](https://tex.z-dn.net/?f=x%5E%7B4%7D%2Bx%5E%7B3%7D-18x%5E%7B2%7D-16x%2B32)
Thus, the required poynomial equation is
