Question

How do i find the intercept on the y and x axis

Answer 1

When you have an equation drawn in a graph, in order to find the x-intercept (intercept on the x axis) and the y-intercept (intercept on the y axis), you need to do the following:

x-intercept: you need to find the value of x where the value of the function is zero.

For example, If you have the function y = ax + b, the x-intercept would be:

`y=0\to0=ax+b\to x=(-b)/(a)`

y-intercept: you need to find the value of y (or the value of the function) where the value of x is zero. For example, for the function y = ax +b, the y-intercept is:

`x=0\to y=a\cdot0+b\to y=b`

In the examples given (linear equations), the x-intercept is the point (-b/a, 0) and the y-intercept is the point (0, b).
