Write the equation of the circle with center (-2, -3) and tangent to the line 2x + 5y = 10. (x – 2)2+(y – 3)2 = 29

(x – 2)2+(y – 3)2 = 5

(x + 2)2+(y + 3)2 = 29

(x + 2)2+(y + 3)2 = 5

The stuff in red i have already been helped with, and for those that have helped me so far, thank you VERY much!

i need to get this done very very soon... i have an online class and I've asked people for help but i haven't had much luck... the instructions the class gives me doesn't even tell me what to do... can i get some help PLEASE... i have a 76 now and with these i will be able to attain a B, and thats all i want...
