Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line. a. y=
b. y=

(a). y = - 4x + 19 ; (b). y = x + 2  

Step-by-step explanation:

Slope "m" of given line is

m = - 4

Slope of parallel line is ( - 4) and perpendicular line is

P(4, 3)

y - = m( x - )

(a). y - 3 = - 4 (x - 4)

y = - 4x + 19

(b). y - 3 = ( x - 4 )

y = x + 2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
