Week 8 – Math 10

This week in math 10 we learned about X and Y intercepts

When determining the X intercept(s) you must turn the Y into a zero and when determining the Y intercept(s) you must turn the X into a zero. Here are 2 examples of both.

X-intercept(s)

  1. y = 2x – 8

0 = 2x – 8

8/2 = 2x/2

X = 4

2.  3y + 2x – 12 = 0

2x – 12 = 0

2x/2 = 12/2

X = 6

 

Y-intercept(s)

  1. 2y + 3x – 12 = 0

2y – 12 = 0

2y/2 = 12/2

Y = 6

2.   2y = x^2 – 60

2y/2 = -60/2

Y = -30
