Answer:
y=0 (x-axis itself)
Step-by-step explanation:
A horizontal line is a line which is parallel to x-axis
It has a slope of 0
Any line whose slope is m can be represented as
y = mx + c
Here m=0
y=c where c is a constant
Any line whose equation is of the above form is a horizontal line.
GJ is perpendicular to IK
20, 31, 33, 35, 55, 57, 58, 59, 72, 73, 79, 86, 87, 88
The data set is split by digit. So 2|0 becomes 20. 5|5 becomes 55. Using this method, the data set is
