Graphic ham issues generally come from subjects such as linear equations, quadratic functions and inequalities. These questions may seem frightening at first, but once you understand what the graph shows and what the question poses, you will see that they are often easier than expected.
Jamb rarely asks you to draw graphics. Instead, you will probably be asked to read, interpret or solve simple graph problems. This guide will show you how to manage questions from the easy means of the easy means and mark full marks.

What to expect in the questions of the graphic
Most questions related to graphics in the amount come into one of these three categories:
- Reading points of a graph (coordinates, slope, interceptions)
- Understand the equations in a straight line (y = MX + C)
- Resolution of quadratic equations using values related to graphics
The goal is to check if you can Connect the equations with visual information in the graph.
Understand the graphics in a straight line
The most common graph uses the graph is the linear graphic, based on the equation:
Y = MX + C
Or:
- M is the slope (or the gradient)
- C is the order y (where the line crosses the y axis)
If we give you two points, you can calculate the slope using:
m = (y₂ – y₁) / (x₂ – x₁)
Once you have the slope and a point, you can find the complete equation of the line. The ham can give you the graphic and ask:
- What is the slope?
- What is the value of Y when X = 3?
- How much does the graph go through the axis?
All this is easy if you understand how to read from a graphic and use a simple substitution.

Understand parabolic graphics (quadratic)
Sometimes Jamb asks questions involving curves, in particular the graph of a quadratic equation like:
y = ax² + bx + c
You are not supposed to draw it, but we could ask you:
- What are the turning points or the maximum / minimum value?
- What is the axis of symmetry?
- What are the roots (Xecepts X)?
The roots are the place where the curve crosses the x axis. These are the solutions to the equation Ax² + Bx + C = 0. You can either solve it directly or read it from a graph if one is given.
Advice to answer questions of the graphic in Jamb
- Read each label On the graph carefully
- Use it ladder To get the right values
- If it is a linear graphic, focus on the slope and where it crosses the Y axis
- For curves, check where it touches or cuts the x axis – these are the roots
- Do not guess – use a simple substitution if you are given an equation
Jamb does not test the skills in drawing. They test how well you understand what the graph represents.

Last words
The graphics in Jamb 2025 have nothing to fear. The key is to understand how equations and forms connect to the graph. With the basic knowledge of the slopes, interceptions and symmetry, you can manage any question linked to the graph with confidence.
As always, more past questions You resolve, the easier it is.
