Chapter 5: The Straight Line Gradient of a Straight Line
Gradient =
Gradient = tan θ
Gradient =

y 2
Vertical Distance θ y 1
x 2
x 1
Horizontal Distance
Intercept
Intercept: The point where the straight line cuts across the axis
x-intercept: The value of x when the straight line cuts across the x -axis
y-intercept: The value of y when the straight line cuts across the y-axis

Chapter 5: The Straight Line
Form 4 Mathematics
Equation of A Straight Line
y = mx + c, m = gradient, c = y-intercept
ax + by = c
Point of intersection of two straight lines is the point which satisfies the both straight lines. line 2
line 1
point of intersection
Parallel Lines
Two parallel lines have the same gradient (m1 = m2) line 1 line 2 m1
