GCSE Secondary Maths Age 13-17 - Graphs: Straight Line Graph - Explained

The video tutorial guides students through graphing a linear equation without pre-drawn axes. It covers setting up axes, creating a table of values, plotting points, and drawing the graph. The tutorial emphasizes checking work and understanding the marking criteria.

What is the first step when you have a graph question without axes?

• Start plotting points immediately.

• Draw the graph directly.

• Use the gradient intercept method.

• Set up the X and Y axes.

When creating a table of values for Y = 2X - 3, what is the recommended starting point?

• Start from the negative end.

• Start from any random point.

• Start from the positive end.

• Start from zero.

What is the Y value when X is 2 in the equation Y = 2X - 3?

• 0

• -1

• 1

• 3

How should the X axis be drawn for the given range of X values?

• From -3 to 2

• From -2 to 3

• From -1 to 4

• From 0 to 5

What is the correct Y value when X is -2 for the equation Y = 2X - 3?

• -8

• -7

• -6

• -5

What is the importance of using a ruler when joining plotted points?

• To make the graph look artistic.

• To make the graph colorful.

• To ensure the line is straight.

• To add extra marks.

How many marks are awarded for correctly plotting the points?

• Two marks

• One mark

• Four marks

• Three marks
