Answer:
The degree of the given polynomial is 3.
Hope it will help :)
We can one theorem to help us find rational roots of this polynomial.
2x^3 + x^2 - 4x - 2
We'll use Descartes' rule of signs.
Because there is 1 sign change, 1 of the 3 roots will be positive.
Now we can make the value of x -1 to see how many negative roots there will be.
-2 + 1 + 4 - 2
There are 2 sign changes, so we know there will be 2 negative roots.
Because of this, we should have 3 real, rational roots.
Answer:
it's 6 dude have a good day for points
The equation of the line written in slope-intercept form is:

Where m is the slope and b is the y-intercept.
You find the slope using the formula:

Where point A coordinates' are (-4,-19) and point B (-6, 4).


Now you find b (y-intercept) substituting in y=-23/2x+b the coordinates of point A or point B:
(I'll use point B coordinates')
y=-23/2x+b
4=-23/2×(-6)+b
4=46+b
b=-42
The equation of the line is y=-23/2x-42
