Answer :
The slopes, I can see that Part A is increasing while Part B is decreasing.
What is the slope?
The term slope is obtained from; the formula;
m = y2 - y1/ x2 - x1
Let us now obtain the slope in each case
1) m = -4 - (-7/2)/4 - (-2)
m = -1/2
2)
x1 = -2
x2 = -1
y1 = -12
y2 = -7
m = (-7) - (-12)/ (-1) - (-2)
m = 5/1
m = 5
3) y = 4.98x + 2
The slope (m) is 4.98
4) m = 2 - 0/5 -2
m = 2/3
5) m = 4 - (-8)/(-4) - 2
m = 12/(-6)
m = (-2)
Part A;
m = 4 - 5/(-3) - (-7)
m = (-1)/4
m = 1/4
Part B;
5/2 - 4/3 - (-3)
m = -3/2/6
m = -1/4
From the slopes, I can see that Part A is increasing while Part B is decreasing.
