Y=--X+2,
Assumeing you're solveing to find the X and Y intercept, you know that y=2 as y=mx+c states that C is the why intercept, in the equation c=2
So, Y=2
To find the x intercept you make Y=0 because when the line hits the X axis Y is always 0
therefore,
0=-x+2
x=2
and it follows that the x intercept is plus to.
so your intercept cordinates are (2,0) and (0,2)
assumeing you want to find the graident you apply y=mx+c and remember that m is the graident, in the eqaution you have -x which is the same a s-1x because -1*x=-x (if you don't get that good luck), so it follows that the gradient=-1, it intercepts the axis at (2,0) and (0,2). If you were not sure if your grad is correct apply DY/DX to one of the questions. nx^n-1.
