A line with a slope of -2 passes through the points (0,d) and (-8,9). What is the value of d?

Verizon [17]

The formula of a slope:

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

We have m = -2 and the points (0, d) and (-8, 9). Substitute:

$\dfrac{9-d}{-8-0}=-2\\\\\dfrac{9-d}{-8}=-2\qquad\text{multiply both sides by (-8)}\\\\9-d=16\qquad\text{subtract 9 from both sides}\\\\-d=7\qquad\text{change the signs}\\\\\boxed{d=-7}$

what is the sum of two numbers is "-7." Two times the first number equals 4 the second number. Find the two numbers.

skelet666 [1.2K]

Answer:

$\sf \text{The numbers are $\dfrac{-14}{3} $ and $\dfrac{-7}{3}$}$

Step-by-step explanation:

Let the numbers be x , y

Sum of two numers = -7

x + y = -7------------(I)

Two times the first number equals 4 the second number.

2x = 4y ----------(II)

Divide both sides by 2

$\sf \dfrac{2x}{2}=\dfrac{4y}{2}$

x = 2y

Subtitute x = 2y in equation (I)

2y + y = -7

3y = -7

y = -7/3

Plugin y = -7/3 in equation (II)

$\sf 2x = 4*\dfrac{-7}{3}\\\\2x = \dfrac{-28}{3}\\\\x =\dfrac{-28}{3*2}\\\\x = \dfrac{-14}{3}$
