16731 should be the answer
A coordinate plane is a two dimensional plane formed by the intersection of a vertical line called y axis and a horizontal line called x axis! Hope this helps
Given:
The equation is

To find:
The number of roots and discriminant of the given equation.
Solution:
We have,

The highest degree of given equation is 2. So, the number of roots is also 2.
It can be written as

Here,
.
Discriminant of the given equation is





Since discriminant is
, which is greater than 0, therefore, the given equation has two distinct real roots.
Y = mx + b
plug in the numbers.
y = 4/3 + 2
