Find the x and z intercepts of the graph of 3x – z \(\leq\) 9
-
(3, -9)
- (-3, 9)
- (-3, -9)
- (-3, 0)
The correct answer is: A
Explanation
Starting from 3x − z \(\leq\) 9
x = 0, substitute the value of x (i.e. x = 0) into the equation 3x − z \(\leq\) 9
3(0) − z \(\leq\) 9
z \(\leq\) − 9
If z = 0
Then, 3x − 0 \(\leq\) 9
3x \(\leq\) 9
x \(\leq\) 3
Intercept of x and z i.e (x,z)
= (3, -9)
