The equation for a horizontal plane through the point (0,−2,−3) is z= -3.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let's assume n is the normal vector for the horizontal plane < 0, 0, 1 > .
The co-ordinate of the point is (0,−2,−3)
The general equation of a plane is -

Thus, The equation for a horizontal plane through the point (0,−2,−3) is z= -3.

Answer:
2m²
to find the area of the □ find the area of the 2 triangles in it the height is 1m and the base is 2m
so do b×h not devided by 2 so you can also find the area of the other triangle so 1x2= 2
