4 0

(1) x = (6.6 +5)/2 = 5.8
(2) m = (4/3)*(13 -4) = 12
(3) p = (2/5)*(13 +3) = 6.4
(4) m = (11.5 -4.5)/3.5 = 2
(5) x = (21.5 -3.5)/9 = 2

A line intersects the points (-5, 1) and (-2,7). What is the slope of the line in simplest form? m=[?}

IrinaK [193]

Step-by-step explanation:

To find slope : y2- y1 / x2 - x1

we have ( -5 , 1 ) which is ( x1 , y1 )

and ( -2 , 7 ) is ( x2 , y2 )

so; 7 - 1 / -2 - (-5)

6/3

= <u>2</u>
