Slope-intercept form

ढाल-अंतःखंड रूप

In Class 9 Mathematics, this topic introduces the slope-intercept form of a linear equation in two variables, written as y = mx + c. Students learn how m represents the slope or rate of change and c shows the y-intercept, where the line meets the y-axis. They practise converting equations into this form, identifying slope and intercepts, plotting the corresponding straight line, and interpreting how changes in the equation affect its graph.
