Maybe you mean y2y8y6 = 2*8*6 *y^3 = 96y^3. This is not 1. Otherwise, I do not know what you could mean by Y 2y8y 6.

1. the answer is 1.
If you mean y-6 = -4(x+1) then it is a straight line equation equivalent to y = -4x+2 when completed whereas the slope is -4 and the y intercept is 2
If for x = -1 we find the same value of y in both equations, then x = -1 will be a part of the solution of the system.Let's suppose that x = -1 is the x-coordinate of the solution of the given systemx + y = 4x - y = 6.x + y = 4-1 + y = 4-1 + 1 + y = 4 + 1y = 5x - y = 6-1 - y = 6-1 - 6 + y - y = 6 - 6 + y-7 = ySince we have two different values for y, we say that x = -1 is not a part of the solution for the given system.
here is the formula... y-y1=m(x-x1) solution.. y-(-1)=m(x-(-1)) m= (0,-5) (-1,-1) -1-5/-1-0= -6/-1 or +6/6 y-(-1)=6(x--1) y+1=6(x+1) y+1=6x+6 y=6x+6-1 y=6x+5 form of y=mx+b y=6x+5 form of Ax+By+C=0 6x-y+5=0
