Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:
The vertex of the parabola is (-2,0)
Step-by-step explanation:
The given function is:
![f(x)=-3x^{2}-6x](https://tex.z-dn.net/?f=f%28x%29%3D-3x%5E%7B2%7D-6x)
Now, in order to find the vertex for the parabola, that is v(h,k), comparing the above equation with the standard form of equation that is
, we get
a=-3, b=-6 and c=0
We know,
and
, therefore
and ![f(h)=f(-2)=-3(-2)^{2}-6(-2)](https://tex.z-dn.net/?f=f%28h%29%3Df%28-2%29%3D-3%28-2%29%5E%7B2%7D-6%28-2%29)
![f(h)=-3(4)+12=-12+12=0](https://tex.z-dn.net/?f=f%28h%29%3D-3%284%29%2B12%3D-12%2B12%3D0)
Thus, the vertex is given as:(h,k)=(-2,0).
