Use the graph to write a linear function that relates y to x

The equation of a line can be predicted easily if two points are given. Thus, the equation of the required line is .

We need to determine the equation of the line with the help of the given graph.

Now, take two points from the graph. The points are ( 1, 4 ) and ( 2, 4 ).

The if a line passed through the two points say , then the equation of the line can be formulated as:

Therefore, apply the formula and solve it further.

Thus, the equation of the line is
