Answer:

Step-by-step explanation:
In order to identify the equation of line from the given graph, we need to find the slope and the y-intercept.
Slope of a line is the ratio of rise to run or change in
over change in
.
The y-intercept is a point on the line for which the
value is 0. In other words, it is on the y-axis.
Here, from the graph,
y-intercept is at point (0,4). So, y-intercept is the
value which is,
.
Also, slope is given as, 
Therefore, the equation of the line is:

"Centi" means 100 so there are 100 centimeters in a meter. 4 times 100 equals 400 so 4 meters is equal to 400 centimeters.
