Convention in algebra is that we use letters such as a, b, c, etc., for parameters and letters such as x, y z, and so on, for variables.
Thus the parameters here are a, b and k. k is the constant of proportionality.
The one that has positive 2 as the y intercept
If you want x, rearrange <span>Z=y+mx as follows: mx = z - y. Then div. all 3 terms by m:
z-y
x = ------- (answer).
m </span>
Answer:
c. x>4
Step-by-step explanation:
subtract 7 from both sides. 11-7=4
x>4
