slope = (6-1)/(4-(-4)) = 5/8
equation:
y = (5/8)x + b, with (4,6) on it, then
6 = (5/8)(4) + b
6 - 5/2 = b
b = 7/2
equation: y = (5/8)x + 7/2
now sub in the given points to see if they satisfy.
e.g. is (80,50) on it??
LS = 50
RS = (5/8)(80) + 7/2
= 50+7/2 ≠ 50
So NO, (80,50) does not lie on the line.
check the other points the same way
A line contains the points (−4, 1) and (4, 6). Select the points below that are also on that line. [Hint: You can use your understanding of slope, or sketch a graph.]
