Answer:

x = ± 8i/11

Step-by-step explanation:

121x2+64=0

x^2 = -64/121

x = +/- √(-64/121)

x = +/- 8i/11

<h3>Answer:   (0, -1)</h3>

Look where the graph crosses the vertical y axis. This point is the y intercept.

In this case, the y intercept is located at (0, -1)

You start at the origin (0,0) and move down 1 unit to get to (0, -1)

Side note: The equation of this line is y = 2x-1
