Substitute the radius to get:

Answer:
D. y = -4x - 6
Step-by-step explanation:
→ Work out gradient of line

→ Write into y = mx + c format
y = -4x + c
→ Substitute ( -2 , 2 ) into the equation to find c
2 = 8 + c
→ Minus 8 from both sides
-6 = c
→ Write full equation y = -4x - 6
2/15
4/5-2/3
convert so they have the same denominator
12/15-10/15
solve
2/15
