Answer:
class b
Step-by-step explanation:
because the mean and median are approximately the same
Answer:
1) m=2/9; y-intercept= 17/3
2) m=7 ; y-intercept= 22
3) m= -2/11 ; y-intercept= 100/11
4) m= 13/19 ; y-intercept= -53/13
Step by Step Explanation:
Use the slope formula to find the slope m.
The slope of the line = (13-5) / -1 = -8.
The y intercept is at y = 5
so the equation is y = -8x + 5
