Step-by-step explanation:
Function A
b= 2.5
5= 1.5m+ 2.5
1.5m= 2.5
m= 1.667
m= 5/3
y= 1.667 x+2.5
.........
Blank 1 : 1.667 or (5/3)
Blank 2: -4.5
rate of change can be positive or negative
Blank 3: Function B
Answer:
C point is the closest to π.
Every point on a line satisfies the equation of that line.
If two lines intersect at one point, that point is a point on both lines, so it must satisfy both lines. Since two different lines can intersect at most at one point, that point is the only point that makes the two equations true.
Check the picture below, so, those red ones are the midpoints you found.

now, that many units are each distance for those "medians", hmmm now, recall that each unit is meant to be 10 meters, so, just multiply each by 10, to get how many meters long each one is.
