'work out the length of the line segment pq.
give your answer correct to 3 significant figures.'

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)

Your maths is very weak try yourself this would improve your skills don't depend on others

The answer is $9.90 with rounding to the nearest tenth
