That line is in point-slope form:
Where 'm' is the slope and (x1, y1) is a point on the line.
Perpendicular lines have opposite slopes. To get the opposite, we take the reciprocal and multiply it by -1.
Reciprocal:
Multiply by -1:
We can plug this slope and the point into point-slope form, and then convert it to slope-intercept form.
Negatives cancel out:
Distribute 1 into the parenthesis:
Subtract 2 to both sides:

Given:
The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.
To find:
The area of the right triangle.
Solution:
Area of a triangle is:
In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.
Now, the area of the given triangle is:
Therefore, the area of the given triangle is 3 square cm.
