A circle touches the x axis at the point P(-3,0) and it's centre C lies on the line 2x+y +1=0. find the: (a) coordinates of C;
(b) radius of the circle;
(c)equation of the circle.​

i think that you should ask google for the answer to that problem because if we don't know it google does

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
