Answer:

r = 5√2

Step-by-step explanation:

Circle Formula: (x - h)² + (y - k)² = r²

(h, k) is center, <em>r </em>is radius.

Since we are given 50 as r², we set equal and solve:

r² = 50

r = √50

r = 5√2

Answer:

slope = $\frac{4}{5}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
