(2, -1)
y = 3X - 1
y = 3x + 1
If: 3x+5 = 4x+1 Then: x = 4
(1, 1)
x + 2 = 3x-1 -2x = -3x = 1,5
It is called the commutative property, a + b = b + a
1
0 because X= -1
Equation of given line: 3x + y = 15 or y = -3x + 15 Slope of given line = coefficient of x = -3 Slope of perperndicular = -1/(slope of given line) = -1 / (-3) = 1/3
2x+5=3x+1 -x=-4 x=4
3x(2x + 1)
