Introduction
Welcome to today’s mathematics tutorial!
In this lesson, we’ll solve linear equation questions commonly found in JAMB, WAEC, NECO, and international exams. We’ll focus on identifying points that lie on a line and determining gradients (slopes) and y-intercepts from given equations.
You can watch the full class in the video below:
Question 1: Identifying Points on a Line
Question:
Which of the following points does not lie on the line: 2y+5x−4= 0
Options:
- A) (0.8, 0)
- B) (1, -0.5)
- C) (0, 2)
- D) (2, 3)

Correct Answer: D) (2, 3)
Question 2: Finding Gradient and Y-Intercept
Question:
A straight line has the equation: 10y = 3x +15
Which of the following is true?
Options:
- A) Gradient = 0.3, Y-intercept = 1.5
- B) Gradient = 3, Y-intercept = 1.5
- C) Gradient = 15, Y-intercept = 3
- D) Gradient = 1.5, Y-intercept = 0.3

Gradient (m) = 0.3
Y-Intercept (c) = 1.5
Correct Answer: A) Gradient = 0.3, Y-intercept = 1.5
