So the answer is that the negative export cannot be part of an expressions numerator here is a website that can help you know or explain more my my answer hope this helped https://www.purplemath.com/modules/exponent2.htm or this website
[x-(-10)]²+(y-6)²=4²
the answer is (<span>x + 10)^2 + (y – 6)^2 = 16</span>
Ok so, this one is a confusing one for me but what I recomend is going on a website call desmos , they have a graphing area there and use y=-4x-7 if I’m right, I do not know so don’t trust me on this
