Svetach [21]

Answer:

3.54

Step-by-step explanation:

Well, we know it has to be 3.5 as our ones, and tenths place, (Thats what I did), and we know it can't be less than 3 for our hundredths place

If we do 0.05, or more as our hundredths place, than we won't be rounding right for the tenths place, so it has to be 3.54

What is an equation of the line that passes through the points (-4, 8) and<br> (2, -1)?
gulaghasi [49]

Answer:

Kayla,  learn this,  :D  more math is based on it.  Just learn it, just memorize the following

Step-by-step explanation:

m = slope

m = rise / run

m = y2 - y1   /  x2 - x1       ( this is still rise over run but in point form )

they give us two points to plug into the above formula

P1 = (-4, 8 )  in the form of ( x1, y 1 )

P2 = (2, -1)  in the form of (x2, y2 )

now plug those into the above formula

m = ( -1 - 8 ) / ( 2-(-4) )

m = -9  /  ( 2 + 4 )

m = -9 / 6

m = - 3/2

since we know the slope now  , we can use the point slope equation of

y - y1 = m ( x - x1)

use the m we found and either point  , P1 or P2

y - 8 = -3/2(x -(-4) )

y-8 = -3/2(x + 4)

y-8 = -3/2x - 6

y = -3/2x -6 + 8

y = -3/2x + 2

there you go  :)
