Points: (-3, 1) and (5, 6) Slope: (1-6)/(-3-5) = 5/8 Equation: y-1 = 5/8(x--3) => 8y-8 = 5(x--3) => 8y = 5x+23 Equation: y-6 = 5/8(x-5) => 8y-48 = 5(x-5) => 8y = 5x+23
4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
The given expression can be simplified to: x-5y
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
140x / 64y divide 5x/8y = > 40x/64y X 8y/5x Note the change of sign and the inversion of the Right hand fraction. Cancel down by '5x' 8/64y X 8y/1 Cancel down by '8y' 8/8 X 1/1 = 8/8 = 1 The answer!!!!

4 + 5x = 1 5x = 1 - 4 5x = -3 x = -3/5 x = -0.6
It is: x-5y simplified
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
The given expression can be simplified to: x-5y
5x+3 = -17 5x = -17-3 5x = -20 x = -4
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
5x-4=8+2x 5x-2x=4+8 3x=12 x=12/3 x=4
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
It is: x-11y simplified
