Work out the length of line segment PQ.

Anarel [89]

The length is:

the square root of [ (the difference in 'x' values)² + (the difference in 'y' values)² ]

D = √ [ (-2-6)² + (5-2)² ]

= √ [ (-8)² + (3)² ]

= √ (64 + 9) = √75 = 5√3 = 8.66 (rounded to 3 sig-figs)

Use the drawing tools to form the correct answers on the graph. Consider this linear function: y = -2x -5 Plot all of the ordere

makkiz [27]

Answer:

see below

Step-by-step explanation:

y = -2x-5

Let x = -6

y = -2*-6 -5 = 12 -5 = 7

Plot the point ( -6,7)

Let x = -5

y = -2*-5 -5 = 10 -5 = 5

Plot the point ( -5,5)

Let x = -2

y = -2*-2 -5 = 4 -5 = -1

Plot the point ( -2,-1)

Let x = -0

y = -2*0 -5 = 0 -5 = -5

Plot the point ( 0,-5)

Let x = 1

y = -2*1 -5 = -2 -5 = -7

Plot the point ( 1,-7)
