A. (-3,5)(0,7)
slope = (7 - 5) / (0 - (-3) = 2/3
y = mx + b
slope = 2/3
(0,7)...x = 0 and y = 7
sub and find b, the y int
7 = 2/3(0) + b
7 = b....this is ur y int (0,7)
so ur equation for this line is : y = 2/3x + 7
b. (6,2)(9,4)
slope = (4 - 2) / (9 - 6) = 2/3
y = mx + b
slope(m) = 2/3
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 2/3(6) + b
2 = 4 + b
2 - 4 = b
-2 = b...this is ur y int (0,-2)
so this equation is : y = 2/3x - 2
so " a " has a slope of 2/3 and a y int of 7 and " b " has a slope of 2/3 and a y int of -2.
ur lines are parallel lines.....parallel lines will have the same slope and different y intercepts <===

The ceramic bowl is 396,000 years older than the other artifact.
Age of ceramic bowl = 400,000
Other artifact = 1/100 times the age of ceramic bowl
Therefore, the age of the other artifact will be :
400,000 × (1/100) = 4000 years
The difference between the age of the ceramic bowl and the other artifact :
Age of ceramic bowl - age of other artifact
400000 - 4000 = 396,000
Hence, the ceramic bowl is 396,000 years older than the other artifact.
