Consider the line , where is a positive number
a) Write the coordinates for and , the points where the line meets the and axes respectively
the points where the line meets the is where
=> (, )
the points where the line meets the is where
=>(, )
b) The area of triangle where is the origin, is units squared. Find the value for
The area of triangle :
where
base is distance from origin to the point
height is distance from origin to the point
so, we have:
then,
=>=>
=>>=>
check the area:
