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)
- 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)
- 2y + 3x – 12 = 0
2y – 12 = 0
2y/2 = 12/2
Y = 6
2. 2y = x^2 – 60
2y/2 = -60/2
Y = -30
