1. Multiple choice questions

Exercise condition:

3 m.

1. The point of intersection of \(3x - y = 4\) and \(x + y = 8\) is

\((5,3)\)
\((3,5)\)
\((4,4)\)
\((2,4)\)

2. Consider four straight lines

(i) \(l_1 : 3y = 4x + 5\)

(ii) \(l_2 : 4y = 3x - 1\)

(iii) \(l_3 : 4y + 3x = 7\)

(iv) \(l_4 : 4x + 3y = 2\)

Which of the following statement is not true?

\(l_1\) and \(l_3\) are perpendicular
\(l_2\) and \(l_3\) are not parallel
\(l_1\) and \(l_4\) are not parallel
\(l_2\) and \(l_4\) are not perpendicular

3. \((2,1)\) is the point of intersection of two lines.

\(x + 3y - 3 = 0; x - y - 7 = 0\)
\(x - y - 3 = 0; 3x + y = 7\)
\(3x + y = 3; x + y = 7\)
\(x + y = 3; 3x + y = 7\)
