Step-by-step explanation:
the y intercept is where 0= x
(0,y)
m is 5
She could switch them around by grouping them into groups of 4s, 3s, 2s, or 5s.
The answer to your problem is
x=5/2
y=5
x=-4
y=2
Tangent always meets radius at 90° angle.
Angle ABC = 90° so Pythagoras' theorem applies.
r² + 4² = (r+2)²
r² + 16 = r² + 4r + 4
12 = 4r
r = 3
