Answer:
Slope:
1) m = 1/3
2) m = 1/2
3) m = 0
Solving for "b":
1) b = -1
2) b = -9
3) b = -2
Evaluate:
1) 0
2) 4
Explanation:
(-3, 6) and (4, 10) m = slope
m = 10 - 6 / 4 + 3
m = 4 / 12
m = 1/3
(6, 2) and (-2, -2)
m = -2 - 2 / -2 - 6
m = -4 / -8
m = 1/2
(-7, -10) and (4, -10)
m = -10 + 10 / 4 + 7
m = 0 / 11
m = 0
7 = 2(4) + b
7 = 8 + b
-1 = b
-11 = 1/2(-4) + b
-11 = -2 + b
-9 = b
4 = -3/4(-8) + b
4 = 6 + b
-2 = b
mx + b m = 2/3, x = 6, and b = -4
= 2/3(6) - 4
= 4 - 4
= 0
mx + b m = -1/2, x = -4, and b = 2
= -1/2(-4) + 2
= 2 + 2
= 4
