Solution for y-(-7)=-2/5(x-(-1)) equation:


x in (-oo:+oo)

y+7 = (-2/5)*(x+1) // - (-2/5)*(x+1)

y-((-2/5)*(x+1))+7 = 0

(2/5)*(x+1)+y+7 = 0

2/5*(x+1)+y+7 = 0

2/5*(x+1)+y+7 = 0

2/5*x+y+2/5+7 = 0

2/5*x+y+37/5 = 0

2/5*x+y+37/5 = 0

2/5*x+y+37/5 = 0 // - y+37/5

2/5*x = -(y+37/5) // : 2/5

x = (-(y+37/5))/2/5

x = -5/2*(y+37/5)

x = -5/2*(y+37/5)
