Description
A straight line in mathematics represents a linear relationship between two variables.
It is commonly expressed by the equation:
y = mx + c
Where:
-
m = slope (rate of change)
-
c = y-intercept (point where the line cuts the y-axis)
Straight lines are studied in coordinate geometry and are used to understand graphs, solve equations, and model real-life situations such as speed, distance, and cost relationships.
