y=8
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
yes
The slope is -2
Subtract the second equation, giving -18 = y so x = -46
3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)
y=8
y=8
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
yes
The slope is -2
Subtract the second equation, giving -18 = y so x = -46
y = 8
4x = -3y+8 3y = -4x+8 y = -4/3x+8/3 So the slope is -4/3 or -1 and a 1/3
First you need to solve for y like this: 6x+3y=8 3y=-6x+8 y=-2x+8/3 Once you have the equation solved for y, the coefficient of x equals the slope: slope = -2
y = 8
