Answer: <u>6 is the slope and 4 is the y-intercept.</u>
Step-by-step explanation:
Based on the question, I feel this is the best way to answer your question. I'm assuming you are in a basic graphing class.
The best, most useful thing for you right now would be to learn slope-intercept form, y = mx + b, where m and b are constants.
Simply add 6x to both sides to get into this form
y = 6x + 4.
In slope-intercept form, m is the slope, and b is the y-intercept. Thus, 6 is the slope and 4 is the y-intercept.

Step-by-step exaplanation
Let x the age of John
Amy's age = x + 9
from question, we get,
John's age + Amy's age = 23
x+(x+9)= 23
=> x + x + 9 = 23
=> 2x = 23 - 9
=> x = 14/2
=> x = 7
