Example 1:
The x-intercept of the line ST is
Solution:
Example 2:
Solution:
Example 3:
Solution:
The x-intercept of the line ST is
Solution:
The x-coordinate for the point of intersection of the straight line with x-axis is -0.4.
Therefore the x-intercept of the line ST is –0.4.
Example 2:
Find the x-intercept of the straight line 2x + 3y + 6 = 0.
Solution:
2x + 3y + 6 = 0
At x-intercept, y = 0
2x + 3(0) + 6 = 0
2x = –6
x = –3
Example 3:
What is the y-intercept of the straight line 12x – 15y = 60?
Solution:
12x – 15y = 60
At y-intercept, x = 0
12(0) – 15y = 60
– 15y = 60
y = –4
