Hi there,
3x - 7y = 14
Sort into y = mx + c form
-7y = -3x + 14
7y = 3x - 14
y = 3/7x - 2
Gradient = 3/7
Lines that are parallel have
the same gradient.
m1 = m2
Using Line Equation:
y - b = m(x - a)
with m = 3/7 and (a,b) = (-6, 10)
y - 10 = 3/7(x -(-6))
y - 10 = 3/7(x + 6)
y - 10 = 3/7x + 18/7
y = 3/7x + 18/7 + 70/7 (10)
y = 3/7x + 88/7
Multiply through by 7
7y = 3x + 88
Hope this helps :-)
