Linear equations are the equations where the highest exponent for the variable is always ‘1’. A linear equation consists of constants and variables and when they are graphed on an X-Y plane, they form straight lines. Graph linear equation calculator is the easy tool which can give the graph of a linear equation.
Example 2: Find any 4 coordinate points for the function, f(x) = x - 2.
Given function: f(x) = x - 2
Let x = 0, then f(0) = 0- 2 = -2 (x, y)= (0, -2)
Let x = -1, then f(-1) = -1- 2 = -3 (x, y)= (-1, -3)
Let x = 1, then f(1) = 1- 2 = -1 (x, y)= (1, -1)
Let x = 2, then f(2) = 2 – 2 = 0 (x, y) = (2, 0)
Hence (0, -2), (-1, -3), (1, -1) and (2, 0) are 4 coordinate points for the given function.
