Glencoe Algebra 2, Chapter 2, 2.3, Section 2.3, Problem 60

In order to find y and x intercepts, we first need to know does they mean...

What is x intercept ?

It can be represented as point of a line intercepting x axis, if any point is to intercept x axis it's vertical position(y) has to be 0.

What is y intercept ?

if any point is to intercept y axis it's horizontal position(x) needs be 0.

We can determine x intercept by setting y = 0


and y intercept by setting x = 0.

so, for the line y= 7x

1) Y intercept (x = 0) is

y =7(0) = 0


2) x intercept (y = 0) is

0 = 7 x
=> x= 0

so x= y =0 so, the point is the origin ie (0,0)
