<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish

Yes, it is a function. It passes the vertical line test.
<u>Answer:</u>
Slope = 6
<u>Step-by-step explanation:</u>
Taking two points on line l to find its slope: (0, 3) and (6, 2).
Slope of line l =
We know that the slope of a line which is perpendicular to another line has a slope which is a negative reciprocal of the other line.
Therefore, the slope of the line which is perpendicular to line l will have a slope of 6.
