Answer:
y = 5x + 2
Step-by-step explanation:
The point-slope form of the equation of the line can be used to advantage. For slope m through point (h, k), that equation is ...
... y = m(x -h) +k
For your point and slope, this is ...
... y = 5(x -1) +7
Simplifying gives the desired equation.
... y = 5x +2
A =πr2
Π = 3.14
r = ½diameter = 25/2 =12.5 inches
∴ Area = 3.14 × 12.5 × 12.5 square inches
Area = 490.625 square inches
