Line l has a slope of...
xz_007 [3.2K]

Hey there! :)

Answer:

Option C.

Step-by-step explanation:

A perpendicular line to 2/3 will be the reciprocal and negative of this fraction. Therefore:

Slope of perpendicular line = -3/2.

Remember, the equation for solving for the slope is:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

We must find points that when plugged into this equation, equal to -3/2.

Plugging in the points in option A:

\frac{2}{3} \neq \frac{-3}{2}

Option B:

\frac{3}{4} \neq \frac{-3}{2}

Option C: This is the correct answer.

\frac{-3}{2} =  \frac{-3}{2}

Option D:

\frac{2}{10}\neq \frac{-3}{2}

An arithmetic sequence is defined as follows:
Dafna11 [192]

The sum of the first 28 terms in the sequence is 5600

<h3>Sum of sequence</h3>

The sum of sequences are known as series. Given the following

a₁ = 92

a₁ = ai-1 - 8

For the second term

a2 = a1 - 8

a2 = 92 - 8

a2 = 84

Determine the sum of first 28th terms

S28 = 28/2[2(92)+(28-1)(8)]

S28 = 14(184+27(8))
S28 = 14(400)
S28 = 5600

Hence the sum of the first 28 terms in the sequence is 5600
