What is the equation of the line that passes through the points ?

(4/5,1/5)(1/2,3/2)
slope = (3/2 - 1/5) / (1/2 - 4/5) = (15/10 - 2/10) / (5/10 - 8/10) = (13/10) / (- 3/10) = 13/10 * - 10/3 = - 130/30 reduces to -13/3

y = mx + b
slope(m) = -13/3
use either of ur points (4/5,1/5)x = 4/5 and y = 1/5
now we sub and find b, the y int
1/5 = -13/3(4/5) + b
1/5 = - 52/15 + b
1/5 + 52/15 = b
3/15 + 52/15 = b
55/15 (reduces to 11/3) = b

so ur equation is : y = -13/3x + 11/3 <==

The answer is lol i dont know

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
