<h3>What is the Circumcenter of Triangle?</h3>
Circumcenter is the point where all three perpendicular bisectors of the three sides of a triangle meet and they are of equal distance from the three vertices of the triangle.
- The line that contains the circumcenter in ΔABC is: <em>line k.</em>
<h3>What is the Orthocenter of a Triangle?</h3>
Orthocenter is the point in a triangle where the three altitudes that are perpendicular to the opposite sides and connect with the vertices of the triangle intersect.
- The line that contains the orthocenter in ΔABC is: <em>line m.</em>
<h3>What is the Centroid of a Triangle?</h3>
The centroid of a triangle is a the point of intersection where all three medians of a triangle. Medians of a triangle connects the vertices to the midpoints of the opposite sides of a triangle.
- The line that contains the centroid in ΔABC is: <em>line l.</em>
<h3>What is the Incenter of a Triangle?</h3>
The incenter of a triangle is the point in a triangle where all three angle bisectors of the vertices of a triangle.
- The line that contains the centroid in ΔABC is: <em>line n.</em>

10 times 3 minus 8 equals 22
9 times 2 plus 1 equals 19
-4 + -1 is -5. So the answer is -5x.
