Question

QUESTION A AND B PLEASEEE I REALLY NEEDED THE ANSWER

Answer 1

a) A ( 7,0 )

B ( 0,7 )

b) y = x

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 =
`((x1+x2)/(2) , (y1+y2)/(2) )`

M =
`((0+7)/(2) , (7+0)/(2))`

M = (3.5,3.5)

Now, Finding the equation of line OM

Slope = m =
`(rise)/(run)`

Slope =
`(3.5-0)/(3.5-0)`

Slope =
`(3.5)/(3.5)`

Slope = 1

Now, the y-intercept,b

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

=>
`y = mx+b`

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

=> b = 3.5-3.5

=> b = 0

Now, the equation becomes

=>
`y = mx+b`

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

=> y = x

This is the required equation
