What are the two point plz help me
evablogger [386]

Your first point should always be shown in the y-intercept following the standard form for slope-intercept form

Y = mx + b

b = y - intercept

In this case your first point would be (0,1)

You next point would be following the slope which is -2x. When you graph a equation always know that it is rise over run. For this line, it would be going from left to right since it is a negative line.

Your second point would go down 2 points from your starting point (0,1) and run 1 to the right in the x-axis, which is also called, (1,-3)

The first two terms of an arithmetic sequences are 7 and 3.
Katyanochek1 [597]

Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n
