Higher November 2020 Unit 1 Q9

(a) Which one of the following equations represents a straight line that is parallel to the line \(2y = 5x - 4\)?
Circle your answer. [1]

\(y = 2{\cdot}5x + 3\)     \(y = 5x - 2\)     \(y = 0{\cdot}4x - 4\)     \(y = -0{\cdot}4x - 2\)     \(2y = -5x + 4\)

(b) Which one of the following equations represents a straight line that intersects the line \(y = 7x - 5\) on the \(y\)-axis?
Circle your answer. [1]

\(y = 7x + 5\)     \(y = 5 - 7x\)     \(y = 3x + 5\)     \(y = 0\)     \(y = 3x - 5\)

(c)

Which one of the five straight lines shown above could represent the equation \(y = -2x + 3\)?
Circle your answer. [1]

Line A     Line B     Line C     Line D     Line E
