Answer:

Y = 2x + 7

Step-by-step explanation:

We know that the slope is 2 so it is 2x

To get the y - intercept of 7 we draw the graph.

if we start at point (-1,-4) and use a slope of 2 the point that lands on the y axis is the y intercept. In this case the y intercept is 7.

The first 5 terms of a sequence are shown below:
nirvana33 [79]

Step-by-step explanation:

To find the formula for the nth term ,

First , find the common difference or common ratio.

Common difference =

T_2-T_1 \\  - 2 - 3 \\  =  - 5

Common ratio =

T_2/T_1 \\  \frac{ - 2}{3}

The common difference applies to the other given numbers for example :

T_3- T_2  =  - 7 - ( - 2) \\  =  - 7 + 2 =  - 5

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is

T_n =a(n-1)d

Where n = no of terms

a= first term

d= common difference

f(x) = 3x + 1

f(-2) is x = -2

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(-2) = 3(-2) + 1
  2. Multiply:                               f(-2) = -6 + 1
  3. Add:                                     f(-2) = -5
