Question 1023162
Hi there,
Sort equations into y = mx + c form:
3x + 2y = 12
2y = -3x + 12
y = -3/2x + 6
Gradient = -3/2
............
6x + 4y = 9
4y = -6x + 9
y = -6/4x + 9/4
Gradient = -6/4 = -3/2
............
Lines that are parallel have
gradients that equal one another.
m1 = m2
-3/2 = -3/2
Hope this helps :-)
