Which answer is an equation in point-slope form for the given point and slope? (1,
Point:
9)
: Slope: 5
oy - 1 = 5(x + 9)
oy - 9= 5 (x + 1)
oy - 9 = 5(x - 1)
o y + 9 = 5 (x - 1)

3rd option

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 5 and (a, b ) = (1, 9 ) , then

y - 9 = 5(x - 1)

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

b.
