Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?
This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).
b. x- and y- intercepts represnts the value of one variable corresponding to the other variable.
