Question

Look at this graph:

Answer 1

For the given graph , slope of the line is equal to  ( 1 / 2 ).

As given in the question,

Form the given graph,

Scale is given by,

On x-axis each unit of the graph represent 1 unit.

On y- axis each unit of the graph represent 1 unit.

Consider two coordinates from the line of the graph,

( x₁ , y₁ ) = ( 1, 2 )

( x₂ , y₂ ) = ( 3, 3 )

Slope of the line = ( y₂ - y₁ ) / ( x₂ - x₁ )

 Substitute the value in the formula of the slope we get,

Slope of the line = ( 3 - 2 ) / ( 3 - 1 )

⇒ Slope of the line = 1 / 2

Therefore, for the given graph , slope of the line is equal to  ( 1 / 2 ).
