Question

Work out the gradient of the line joining a pair of coordinate (-4, -5), (–8, 7)

Answer 1

Answer:

We know that the slope of the line joining two points (x

1

,y 1) and (x 2 ,y 2 ) is:

m= x 2 −x 1

y 2 −y 1

Here, the given points are (4,−8) and (5,−2), therefore, the slope of the line is:

m= x 2 −x 1y 2−y 1

= 5−4−2−(−8)

= 1−2+8 =6

Hence, the slope of the line is 6.

Answer 2

Answer:

The coordinate of (-4,-5),(-8,7)are:

(-4,-5)=(x1,y1)

(-8,7)=(x1,y)
