Answer:

C) 3, 6, 11, 18...

Step-by-step explanation:

The explicit form of a pattern is :a_n = n^2 + 2

We are supposed to find the first four terms

Substitute n = 1

a_1=1^2+2=3

Substitute n =2

a_2=2^2+2=6

Substitute n =3

a_3=3^2+2=11

Substitute n =4

a_4=4^2+2=18

The first four terms are 3,6,11,18

So,option C is true

C) 3, 6, 11, 18...

What is the slope of (8,3) and (-4,-6)?
Nonamiya [84]

<u>Answer:</u> The slope of the line formed by these two points is \frac{3}{4}

<u>Step-by-step explanation:</u>

To calculate the slope, we use the formula:

Slope=\frac{y_2-y_1}{x_2-x_1}

For the coordinates given:

x_1=8\\y_1=3\\x_2=-4\\y_2=-6

Putting values in above equation, we get:

Slope=\frac{(-6-3)}{(-4-8)}\\\\Slope=\frac{-9}{-12}\\\\Slope=\frac{3}{4}

Hence, the slope of the line formed from these two coordinates is  \frac{3}{4}
