Answer:
x = 8, y = 1
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
4y = 4 ( divide both sides by 4 )
y = 1
Also
=
( cross- multiply )
x = 8

The equation of parabola is
Comparing with the vertex form of the parabola:
Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p
Thus, the focus is given by
And the directrix is given by
Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.

Step-by-step explanation:
Assume that each cell on the grid represents one unit. One can use the formula, () to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,
