Line p because the line crosses the y axis at -2
Answer:
Given the equation, the radius of the circle is 7.
Step-by-step explanation:
We are given the equation, x² + y² = 49.
In order to find the radius, we have to calculate the square root of 49. This is because the original form of the equation is x² + y² = r².

So, the radius of the circle is 7.
Always complete the math inside a bracket first.
x-4x = -3x
So the answer is d. 3x - 5y
