Question

[ please help! ] The graph below shows a line segment PQ.

What is the slope of the line segment PQ? (3 points)


-2

-1/2

1/2

2

Answer 1

Slope of the line segment PQ is 1/2.

Explanation:

We are given with a line connecting two points P and Q.

The coordinates of P are (4,4) and the coordinates of Q are (-2,1).

Slope of line joining two points
`(x_(1),y_(1))` and
`(x_(2),y_(2))`

is given by the formula
`(y_(2)-y_(1))/(x_(2)-x_(1))`

Hence the slope of the line PQ is
`(1-4)/(-2-4)=(-3)/(-6)= (1)/(2)`

Therefore correct option is 'C' that is 1/2.
