Answer:
The direction is negatively correlated and it is a strong correlation. The answer is thus strong negative.
Step-by-step explanation:
in short, you simply pick a few random "x" values, to get the "y", and that's your point, for example say x = 2, then y = -(2)² - 4 => y = -8, that gives us the point of (2, -8), and so on.
we can start off by finding the vertex, the U-turn of the graph, and then just pick a point to its left side and a point to its right side, and we can get the vertex of that by
and since it's a vertical parabola, the axis of symmetry comes from the x-coordinate of the vertex, namely x = 0, check the picture below.
The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)
<h3>How to solve the equations?</h3>
The system of equations is given as:
y = -x² + x + 2
y = -x + 3
From the graph in the complete question, we have the following point of intersection between the equations
(x,y) = (1,2)
The point of intersection between the equations is the solution
Hence, the solution of the graphed system of equations is (1,2)
