Draw a graph or use graph paper. The first number is X axis wich would go horizontal ( ------), to remember that term think of a horses back, Y axis which is your second number goes vertical (|) up and down.
Answer:
y=-10x
Step-by-step explanation:
y=-10x
y/x=-10
Given that the vertex of the parabola is (4,-3)
The parabola passes through the point (2,-1)
We need to determine the standard form of the equation of the parabola.
<u>Standard form of the equation of the parabola:</u>
The standard form of the equation is
where the vertex is (h,k) and a is the constant.
Substituting the vertex (4,-3) in the above equation, we get;
---------------(1)
Substituting the point (2,-1) in the above equation, we have;





Thus, the value of a is 
Substituting the value of a in the equation (1), we get;

Thus, the standard form of the equation of the parabola is 
Answer:
No
Step-by-step explanation:
His answer is incorrect. If we round the dimensions, 3.76 m is almost 4 m, and 5.49 m is almost 5.5 m. 4 × 5.5 = 22. So his answer should be close to 22 m².
