You can put this solution on YOUR website! f(x)=-x^2-4x+3
f(-2)=-4+8+3
=7
.
3(x-2)=-4(x+8)+10
3x-6=-4x-32+10
3x-6=-4x-22
7x=-16
x=-16/7
.
f(x)=x/x-4
Domain of x is all real numbers except 4. Division by zero not allowed.
.
m=-3/7
one point on the graph is (0,-4)
y-y[1]=m(x-x[1])
y-(-4)=-3/7(x-0)
y+8=-3x/7
y=(-3x/7)-8
