Which of the following is an arithmetic sequence?

A. 4, 7, 10, 13, 16
B. 1, 2, 4, 7, 10
C. 3, -3, 4, -4, 5, -5
D. 2, 4, 8, 16, 32

A is the answer

Step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
