A-Level Maths H1 Quiz - Graphs Coordinate Geometry (Answer Key)

Topic: Graphs & Coordinate Geometry
Version: 1 of 5
Total Marks: 40 (2 marks per question)

Section A: Lines and Basic Coordinate Geometry

Q1. [2 marks]
Gradient $m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{6 - (-3)}{5 - 2} = \frac{9}{3} = 3$ .
Answer: Gradient = 3.
Teaching note: Gradient measures steepness; subtract y's over x's in the same order. Common mistake: reversing order inconsistently.

Q2. [2 marks]
Parallel line has same gradient $m = 3$ . Through $(4,1)$ : $y - 1 = 3(x - 4) \Rightarrow y = 3x - 12 + 1 = 3x - 11$ .
Answer: $y = 3x - 11$ .
Marking: 1 mark gradient, 1 mark equation.

Q3. [2 marks]
Gradient $AB = \frac{5-2}{3-1} = \frac{3}{2}$ ; gradient $BC = \frac{8-5}{5-3} = \frac{3}{2}$ . Same gradient and shared point B ⇒ collinear.
Answer: Yes, collinear because gradients equal.
Note: Also check via area of triangle = 0.

Q4. [2 marks]
Midpoint $= \left(\frac{-2+6}{2}, \frac{4+(-2)}{2}\right) = (2, 1)$ .
Answer: $(2, 1)$ .

Q5. [2 marks]
$x$ -intercept: set $y=0 \Rightarrow 2x=6 \Rightarrow x=3$ .
$y$ -intercept: set $x=0 \Rightarrow -3y=6 \Rightarrow y=-2$ .
Answer: $(3,0)$ and $(0,-2)$ .

Section B: Curves, Graphs and Transformations

Q6. [2 marks]
$y$ -intercept at $x=0$ : $y=e^0=1 \Rightarrow (0,1)$ . Asymptote: $y=0$ (x-axis). Curve increasing, passes through (0,1).
Answer: y-int (0,1), asymptote $y=0$ .
Sketch: rising curve left to right, never touching x-axis.

Q7. [2 marks]
$y=\ln(x-3)$ is translation of $y=\ln x$ by 3 units right. Vertical asymptote moves from $x=0$ to $x=3$ .
Answer: Translation right by 3; new asymptote $x=3$ .

Q8. [2 marks]
$e^{2x}=5 \Rightarrow 2x = \ln 5 \Rightarrow x = \frac{1}{2}\ln 5$ .
Answer: $x = \frac{\ln 5}{2}$ .

Q9. [2 marks]
Solve $x^2 = 4 - x \Rightarrow x^2 + x - 4 = 0$ . GC gives positive root $x \approx 1.56$ .
Answer: $x \approx 1.56$ .

Q10. [2 marks]
No real roots ⇒ discriminant $<0$ : $k^2 - 16 < 0 \Rightarrow -4 < k < 4$ .
Answer: $-4 < k < 4$ .

Midpoint $(2,3)$ , gradient of segment $= \frac{6}{4}=1.5$ , perpendicular gradient $= -\frac{2}{3}$ .
Equation: $y-3 = -\frac{2}{3}(x-2) \Rightarrow y = -\frac{2}{3}x + \frac{13}{3}$ .
Answer: $y = -\frac{2}{3}x + \frac{13}{3}$ .
