Linear Function[edit | edit source]
Linear Function is a function of a Straight Line
General Form[edit | edit source]
Straight Line goes through point (0,0)[edit | edit source]
For every x there is y = x
- x | y
- -2 | -2
- -1 | -1
- 0 | 0
- 1 | 1
- 2 | 2
If f(x) = y Then f(x) represents a Straight Line through point (0,0) with Slope equals 1
Straight Line goes through two points[edit | edit source]
If there is a Straight Line goes through 2 points (xo,yo) , (x,y)
Straight Line goes through Two Intercept Points[edit | edit source]
When
- x = 0 y = b
- y = 0 x = a
Function of a Straight Line that cuts the x axis at (0,a) and the y axis at (0,b)
