Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , thus
y = x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7
y = x - 7 ← equation of line
Answer:
22.8906 sq in
Step-by-step explanation:
SA of a sphere = 4 π
r = 2.7 / 2 = 1.35
4 x 3.14 x = 22.8906
