Question

Hey can someone help me and check my answers? thanks <3

Answer 1

Remember
x^-m=1/(x^m)
u^-3=1/(u^3)
1/(u^3)=1/125
therefor
u^3=125
u=5




x=-3
easy
y=-3-13
y=-16
correct



normally, y is output
(x,y)
chose al second numbers
0,3 are all acceptable
B and D




y=mx+b
m=-3
y=-3x+b
sub point
(x,y)
(1,-2)
-2=-3(1)+b
-2=-3+b
1=b
y=-3x+1

remember (x,y) you keep swtiching those
