Points: (4, 8) and (2, -2) Slope: (8--2)/(4-2) = 5 Equation: y-8 = 5(x-4) => y = 5x-12 Equation: y--2 = 5(x-2) => y = 5x-12 So straight line equation is: y = 5x-12

ANSWER: 12 and -6x * y = 72x = 72/y Equation 1x + y = 6 Equation 2Substitute Eq.1 to Eq.2-72/y + y = 6multiply both sides of the equation by yy (-72/y + y ) = 6* y-72 + y2 = 6yy2 - 6y - 72 = 0(y- 12) (y + 6) = 0y = 12 ; y = -6x =-12 ; x = 12Take x = 12 and y = -6
y = x - 4 × 2 + 12 y = x - 8 + 12 y = x - 20 That is the simplest form of the equation, as you can only solve completely by having only 1 variable to solve.
If you mean: y-6 = 2(x+3) then y = 2x+12 whereas 2 is the slope and 12 is the y intercept
