   Q.Slope of the line which makes an angle of $30°$ with the positive direction of $y$-axis measured anticlockwise is

   (a) $-\sqrt{3}$

   (b) $-\dfrac{1}{\sqrt{3}}$

   (c) $\dfrac{1}{\sqrt{3}}$

   (d) $\sqrt{3}$

   ›Reveal solutionSolution

   Convert the angle measured from the $y$-axis to the equivalent angle measured (anticlockwise) from the $x$-axis, then take its tangent as the slope.

   Slope is defined as $\tan\theta$ where $\theta$ is the angle the line makes with the positive $x$-axis, measured anticlockwise. The positive $y$-axis itself is at $90°$ from the positive $x$-axis. If the line makes a further $30°$ with the positive $y$-axis (measured anticlockwise, i.e. swinging past the …

   Q.The slope of any line parallel to X-axis is:

   (a) $0$

   (b) $1$

   (c) $-1$

   (d) Not defined.

   ›Reveal solutionSolution

   A line parallel to the X-axis is horizontal, so its slope $m=\tan\theta$ with $\theta=0°$, giving $m=0$.

   Q.The slope of the line passing through the points $(3, -2)$ and $(7, -2)$ is

   (a) 0

   (b) 1

   (c) 4

   (d) -1

   ›Reveal solutionSolution

   The slope is $0$ — the line through these points is horizontal.

   The slope formula is $m = \dfrac{y_2-y_1}{x_2-x_1}$.

   For $(3,-2)$ and $(7,-2)$: $m = \dfrac{-2-(-2)}{7-3} = \dfrac{0}{4} = 0$.

   Q.The slope of the line 3x − 4y + 10 = 0 is 4/3. (True/False)

   ›Reveal solutionSolution

   Writing the line in slope-intercept form gives the true slope, which does not match the statement.

   Line: $3x - 4y + 10 = 0$

   Solve for $y$: $4y = 3x+10 \Rightarrow y = \dfrac{3}{4}x + \dfrac{10}{4}$

   Q.Fill in the blank: The slope of the line $6x + 3y - 5 = 0$ will be ____.

   ›Reveal solutionSolution

   Rearranging $6x + 3y - 5 = 0$ into $y = mx + c$ form shows the slope $m = -2$.

   Starting from $6x + 3y - 5 = 0$, solve for $y$:

   $3y = -6x + 5$

   $y = -2x + \dfrac{5}{3}$
