Honors Pre-Calc question.

-10

Step-by-step explanation:

2, -1, -4, -7.

Sum =  -10.

Step-by-step explanation:

The first 4 terms are:

5 - 3(1), 5 - 3(2), 5 - 3(3), 5 - 3(4).

= 2, -1, -4, -7.

The sum of the 4 terms

= 2 - 1 - 4 - 7

= 2 - 12

= -10.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
