Answer:

Its the first choice.

Step-by-step explanation:

an = the nth term. so:

a1 = 6(1) + 1 = 7

a2 = 6(2) + 1 = 13

a3 = 6(3) + 1 = 19

The common difference is 6.

Answer:

7, 13, 19, 25, 31

Step-by-step explanation:

aₙ = 6n + 1

n = 1: a₁ = 6 × 1 + 1 = 6 + 1 = 7

n = 2: a₂ = 6 × 2 + 1 = 12 + 1 = 13

n = 3: a₃ = 6 × 3 + 1 = 18 + 1 = 19

n = 4: a₄ = 6 × 4 + 1 = 24 + 1 = 25

n = 5: a₅ = 6 × 5 + 1 = 30 + 1 = 31

Given :-

A graph is given to us .

To Find :-

The equation in slope intercept form .

Answer :-

From the given graph , we can see that the line passes through y axis at (0,5) . So the y intercept is 5 . And the slope of the line is 5/2 = 2.5 . So ,

$\sf\longrightarrow$ y intercept = 5 .

$\sf\longrightarrow$ slope = 5/2 .

Now here we can use the slope intercept form as ,

$\sf\longrightarrow$ y = mx + c

$\sf\longrightarrow$ y = 5/2x + 5

Hence the required answer is y = 5/2x + 5.
