Find the x and z intercepts of the graph of 3x - z \(\leq\) 9
A
(3, -9)
B
(-3, 9)
C
(-3, -9)
D
(-3, 0)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
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)
