Answer:
No solution.
Step-by-step explanation:
If two lines have the same slope, but different y-intercepts, then they are parallel, meaning they never touch, meaning they have no solutions. However, if two lines have the same y-intercepts but different slopes, then the only solution will be at the y-intercept. However, if two two lines are exactly the same, then there are infinitely many solutions.
The slope is 2.

see explanation
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 9 ← is in this form
with centre (0, 0 ) and r = = 3
this then is the equation of a circle whose centre is (0, 0 ) with radius 3
You can try the ac method.
1. Try to factor a common factor from all terms.
2. Multiply ac.
3. Find two factors of ac that add to b, call them p and q.
4. Rewrite the trinomial with the bx term broken up into into px + qx.
5. Factor by grouping.
