Answer to Problem 15SGR

The coordinates of the orthocentre is (2,3) .

Explanation of Solution

The line that contains the altitude of the triangle are concurrent and the point of intersection is known as the orthocentre.

In order to determine the orthocentre, intersection points are needed to be determined.

The slope of the line EF is 3−76−0=23 then the slope of the altitude is 32 . Thus, the equation of the altitude is,

  y−y1=m(x−x1)y−0=32(x−0)y=32x

Then the equation of the altitude from E(0,7) to DF¯ . Then, the slope of the DF¯ is 3−06−0=12 . Then, the slope of the altitude is -2 and the equation of the altitude is,

  y−7=−2(x−0)y=−2x+0+7y=−2x+7

Then,

  32x=−2x+7x=2

The y coordinate is,

  y=32x=32(2)=3

Thus, the coordinates of the orthocentre is (2,3) .
