Because we know how large each hand is, we can multiply the number of hands by the amount of inches each one represents to find the total number of inches.

If anyone could help me with this I'd be really grateful.

Lostsunrise [7]

Answer:

d = 9

Step-by-step explanation:

Calculate the slope m of line AB and equate the result to 3

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(d, 21)

m = $\frac{21-6}{d-4}$ = $\frac{15}{d-4}$ = 3 ( multiply both sides by d - 4 )

15 = 3(d - 4), that is

15 = 3d - 12 ( add 12 to both sides )

27 = 3d ( divide both sides by 3 )

9 = d

What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)?

Nat2105 [25]

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (9, 1) and (4, 16). Substitute:

$m=\dfrac{16-1}{4-9}=\dfrac{15}{-5}=-3$

$y-1=-3(x-9)$
