Someone please help!! Determine the intercept of the line. ​
hichkok12 [17]

Answers:

x intercept is (-7.5, 0)

y intercept is (0, 5.5)

=========================

How to get these answers:

Simply look at where the graph crosses the x axis to determine the x intercept. This is directly halfway between the -8 and -7, so the line crosses through -7.5 on the x axis meaning that the x intercept is located at (-7.5, 0)

Similarly, the y intercept is (0, 5.5) as it crosses exactly halfway between the 5 and 6 on the y axis.

Any point is of the form (x,y)

The x intercept always has y = 0. The y intercept always has x = 0.
