Answer:
y = -5/7x + 27/7
Step-by-step explanation:
y2 - y1 / x2 - x1
1 - 6 / 4 - (-3)
-5 / 7
= -5/7
y = -5/7x + b
1 = -5/7(4) + b
1 = -20/7 + b
27/7 = b
exact form 32/21
decimal form 1.523809 repeating
mixed number form 1 11/21
7.5%
280 - 259 = 21
21 / 280 = 0.075 = 7.5%
B
2 : 5, or 2/5
4 : (3 + 3 + 4) =4 : 10 = 2 : 5
