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

Select all of the equations that represent linear relationships. 5 + 2y = 13 y = 1/2x^2+7 y – 5 = 2(x – 1) y/2 = x + 7 x = –4
Luden [163]

Answer:

FIRST OPTION.

THIRD OPTION.

FOURTH OPTION.

FITH OPTION.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y=mx+b

Where m is the slope, b the y-intercept and the exponent of x is always 1 or 0.

Solve for y from  the equations shown below:

5+2y=13\\2y=8\\y=4

(In this linear function the slope is 0)

y-5=2(x-1)\\y=2x-2+5\\y=2x+3

(It is a linear function)

\frac{y}{2}=x+7\\ y=2(x+7)\\y=2x+14

 (It is a linear function)

Equation of the line whose slope is not defined:

x=-4

den301095 [7]
P(both red)=(10/17)(9/16)
P(both blue)=(7/17)(6/16)

P(both same)= sum of above 2 = (90+42)/(16*17)=132/(16*17)=<span>0.485

coz both same means  both blue or both red
