Answer:
D. 3
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
y=mx + b (slope intercept form) m= slope, b =y-intercept
slope=rise/ run
Step-by-step explanation:
The slope intercept form is a line (straight line)
y = 3x - 7 slope 3 (rise=3, run = 1), y-intercept = -7
y = - 1 3 x + 7 slope -13 , y-intercept = 7
y=-3x - 7 slope -3, y-intercept = -7
The correlation coefficient r of the data set is <em>-0.28</em>
It’s A
Explanation / when you multiply 7 by -9 you get -63
