This exercise is about creating two-dimensional shapes. The resulting shape is a quadrilateral - Square. See the attached for the lines drawn.
What was noticed about the two lines drawn?
- The two lines are drawn each had parallel pairs; and
- They were perpendicular to one another.
When two lines intersect with one another such that they create a right angle, perpendicularity has occurred and both lines are said to be perpendicular to one another.
Hence:
- AB ⊥ BC
- BC ⊥ CD
- CD ⊥ DA; and
- DA ⊥ AB.

Answer:
y= x
Step-by-step explanation:
Given the two points:
- Origin (x1, y1) = (0, 0)
- The point (x2, y2) = (5, 9)
Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).
=>Time, x the independent variable,and distance is the dependent variable.
We have the standard form of a linear equation is:
y= mx + b where a is the slope
We know that, the slope of the function is:
m =
In this situatuon, m =
=> y= x + b(1)
The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:
0 = *0 + b
<=> b = 0
So our equation that the graph represents is: y= x
2 sack of cement is needed to cover entire floor of Joel
<em><u>Solution:</u></em>
Given that a sack of cement is enough to cover a floor with a total area of 45 sqft
Joel’s floor length is 8ft by 7ft
To find: Number of sacks needed to cover entire floor of Joel
Let us first find area of Joel's floor
Since the floor is generally of rectangular, we can use area of rectangle
<em><u>So the total area of floor with length 8 feet and width 7 feet is:</u></em>
Thus the total area of floor is 56 square feet
<em><u>Let us now find number of sacks needed to cover entire floor</u></em>
Given that, one sack of cement covers 45 square feet
Since Sack of cement cannot be in point value hence we can say 2 sack of cement is required.
