Answer:
Given
in a circle
Diameter ( d) = 36 cm
Then we have the formula that
Radius (r) = d / 2
= 36 / 2 = 18 cm
Greatest Common Factor:
We look for a number that can simultaneously go into both numbers:
4: 28 70
7 10
No other number can go into both at the same time.
Therefore GCF is 4.
Use the given slope and point to substitute into the point-slope formula
y - y1 = m (x - x1)
Slope-intercept form:
y = -5
Point-slope form:
y + 5 = 0 • (x + 7)
B. Not proportional.
30 ÷ 3 = 10
36 ÷ 3 = 12
