What is the equation of the line represented by the table below? Х-2,-1,0,1,2 y16,11,6,1,-4
pashok25 [27]

Answer:

y = -5x + 6

Step-by-step explanation:

General equation of a line : y = mx + c......where c is intercept

To find m pick any two points..

(-2, 16) and (-1, 11)

Using (y - y¹) / (x - x¹)

(11 - 16) / (-1 - [-2]) = -5 / 1

= -5

To find c sub with any point for (x, y) and m

using (2, -4)

y = mx + c

-4 = -5(2) + c

-4 = -10 + c

6 = c

Input the values of m and c in the general equation without x and y

; y = -5x + 6

Describe order of operation and give an example
ryzh [129]

Order of Operation is commonly referred to as PEMDAS, an acronym for "Please excuse my dear aunt Sally," which references the order in which operations should  be calculated when solving a math problem.

P = parentheses

E = exponent

M = multiply

D = divide

A = add

S = subtract

So you don't always have all of these components, but you consider the ones present in the problem in front of you.    If there is no multiplication, but there is division and a set of parentheses, then you FIRST solve what's inside the parentheses, then  you divide.    If you have some examples, I'll show you.
