Graphs of Linear Equations
linear equation is a line graph. A line graph has a simple equation like y= ax+b, y= ax-b or just y= ax
By observing a line graph we can find its linear equation.
To write the linear equation from graphs we can use the slope intercept formula y = mx +c
Sometimes mere observation of a set of coordinates helps us to get the linear equation.
Here let us do 3 graphs, the first is written by mere observation., the second graph is of the form y = k and the third equation is found by using y = mx +c.
