Answer: y=1/2x-3
Step-by-step explanation:
Slope-intercept form:y=mx+b
m=y2-y1/x2-x1
-1-(-2)/4-2=1/2
y=1/2x+b
-1=1/2(4)+b
-1=2+b
b=-3

(26/25) x (15/28) x (8/39)
Divide top and bottom by 3 :
(26/25) x (5/28) x (8/13)
Divide top and bottom by 5 :
(26/5) x (1/28) x (8/13)
Divide top and bottom by 4 :
(26/5) x (1/7) x (2/13)
= 52 / 455 = 0.11429... (rounded)
