Answer:

a) A ( 7,0 )

   B ( 0,7 )

b) y = x

Step-by-step explanation:

Since the radius is 7,

So,

a)   A ( 7,0 )

     B ( 0,7 )

b) The coordinates of O are (0,0)

while M are to be founded.

Using Midpoint formula to find M

M = [tex](\frac{x1+x2}{2} , \frac{y1+y2}{2} )[/tex]

M = [tex](\frac{0+7}{2} , \frac{7+0}{2})[/tex]

M = (3.5,3.5)

Now, Finding the equation of line OM

Slope = m = [tex]\frac{rise}{run}[/tex]

Slope = [tex]\frac{3.5-0}{3.5-0}[/tex]

Slope = [tex]\frac{3.5}{3.5}[/tex]

Slope = 1

Now, the y-intercept,b

Putting M(3.5,3.5) in slope intercept equation to get y-intercept, b

=> [tex]y = mx+b[/tex]

=> 3.5 = (1)(3.5) + b

=> b = 3.5-3.5

=> b = 0

Now, the equation becomes

=> [tex]y = mx+b[/tex]

=> y = (1)(x) + (0)

=> y = x

This is the required equation
