What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point (4,
1)?
y-1 = -2(x – 4)
y-1= - = (x-4)
y-1 = 7 (x-4)
y - 1 = 2(x-4)

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
