(n+1)x 2=10
2n+2=10
2n=8
n=4
The commutative property of addition means that when you see a problem, you change the order. The co in commutative means change order. That's what my teacher told me.
1) 6x-7y=-11
2) x=-2
3) y=-4x+1
4) y-5=3(x-1)
Equation of the given line will be :
now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.
now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.
Okay, so I had to resort to the calculator since I couldn't figure out how to do it, anyway here.
(-0.08928571428) -this is the answer according to it id says take a few numbers and see what answer fits it the most but yeah, I didn't help much.
