Answer:

11 and 74

Step-by-step explanation:

To find the second and fifth terms substitute n = 2, n = 5 into the rule, that is

a₂ = 3(2)² - 1 = 3(4) - 1 = 12 - 1 = 11

a₅ = 3(5)² - 1 = 3(25) - 1 = 75 - 1 = 74

Write the slope-intercept form of the equation of each line
navik [9.2K]

Answer: y= 3x-1

Step-by-step explanation:

Equation of a straight line:

y = mx + b ------(i)

Step by Step Solution:

Step 1: Calculating Slope (m).

m =

y2-y1

x2-x1

m =

2--1

1-0

m =

3

1

m = 3

Now putting value of m in equation (i)

y = 3x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (0,-1) for calculating y-intercept:

y = mx + b

-1 = 3(0) + b

-1 = 0 + b

-1 = b

b = -1
