Step-by-step explanation:
<u>Expansion</u>
<-- Stop here if this is what you need
<u>Factorization</u>
<u />
We know from vertex form that the vertex of the parabola is and when factored, the zeroes are and .
Solve for x in 2y = x + 1
x = 2y - 1
Substitute x = 2y - 1 into -2x - y = 7
-5y + 2 = 7
Solve for y in -5y + 2 = 7
y = -1
Substitute y = -1 into x = 2y - 1
x = -3
Therefore,
<u>x = -3</u>
<u>y = -1</u>
