Which equation represents the line passing through the points (3, 2) and (-9, 6)?

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3  and  y1 =2

let  A(3,2)    B(-9,6)

the slope is : m =   (YB - YA)/(XB -XA)

(6-2)/(-9-3)  =4/(-12)  = -1/3

the slope is   m = -1/3

The equation is :  y – y1 = m(x – x1)

y-2 =-1/3 ( x-3)

or : 3y-6 = -x+3

the answer is 31.27mph

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
