Answer:
y= 2x-3 m=2 b= -3
Step-by-step explanation:
we distribute 2(x-2)
y-1 = 2(x-2)
y-1 = 2x-4
then add one to both sides
y-1= 2x -4
+1 +1
since it is negative four and you are adding one it would be -3
y= 2x -3 that is your slope intercept form.
y= mx +b so m=2 and b= -3
Answer:
The equation of the circle having centre (-5,-9) and radius r=3 is
x² + 10 x +y² + 14 y + 65 = 0
Step-by-step explanation:
<u>Explanation</u>:-
From graph The centre of the circle C( -5 , -7)
The radius of the circle r = 3cm from the centre of the given circle
The equation of the circle
From graph the centre ( h, k) = ( -5,-7) and r = 3cm
x² + 10 x +25 +y² + 14 y + 49 =9
x² + 10 x +25 +y² + 14 y + 49 -9=0
The equation of the circle
x² + 10 x +y² + 14 y + 65 = 0
