find the equation of the line using y=
6/7, (1,-8)
9, (9,1)
I will do the first, you do the second
y = (6/7)x + b
but (1,-8) is on it, so
-8 = (6/7)(1) + b
-56 = 6 + 7b
7b = -62
b = -62/7
y = (6/7)x - 62/7
6/7, (1,-8)
9, (9,1)
y = (6/7)x + b
but (1,-8) is on it, so
-8 = (6/7)(1) + b
-56 = 6 + 7b
7b = -62
b = -62/7
y = (6/7)x - 62/7
