Write an equation of the line that passes through the given points. (-2,8) and (1,2) (write answer in slope-intercept form.)

The slope-intercept form of the line that passes through the points (-2,8) and (1,2) is y=-2x+4

Step-by-step explanation:

Given:  

Points(x,y)= )= (-2,8)

Points(x1,y1)=  (1,2)

To find:

Equation in slope-intercept form=?

Solution:

The slope intercept form of a line is y= mx + b  

Where m= the slope

STEP 1: Finding the slope value

Substituting the points in the formula we get,  

STEP 2: Finding the value of  b

Substituting the slope value in the equation we have

y=mx+b,

y= -2(x)+b

y= -2(x) + b

substituting x and y from the points given,

8=-2(-2) + b

8=4+b

8-4=b

b =4

STEP 3: Formation of slope intercept equation

Substituting b and m in the equation of slope we get,

y= mx + b  

y= -2x+4.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
