2. Finding the values of a, b and c

Question:

3 m.

Write each of the following in the form of \(ax + by + c = 0\) and indicate the values of \(a\), \(b\) and \(c\) in each case.

(i) \(2x = -y + 2.5\)

\(a=2\), \(b=1\),\(c=2.5\)
\(a=2\), \(b=-1\),\(c=-2.5\)
\(a=-2\), \(b=1\),\(c=-2.5\)
\(a=2\), \(b=1\),\(c=-2.5\)

(ii) \(2x + 3y = 4.37\)

\(a=2\), \(b=3\), \(c=-4.37\)
\(a=2\), \(b=-3\), \(c=-4.37\)
\(a=2\), \(b=3\), \(c=4.37\)
\(a=-2\), \(b=3\), \(c=-4.37\)

(iii) \( y = 5x\)

\(a=5\), \(b=-1\), \(c=0\)
\(a=-5\), \(b=-1\), \(c=-1\)
\(a=-5\), \(b=1\), \(c=0\)
\(a=5\), \(b=1\), \(c=0\)
