formula: y = mx + b
current points we know:
m = 1/2
x = 10
y = 0
so we solve for the b value.
0 = 1/2 (10) + b
0 = 5 + b
(inverse operation we subtracted 5 on both sides)
-5 = b
so the equation for a line with slope 1/2 passing through the point (10,0) is
y = (1/2)x + (-5) or y = (1/2)x - 5
(not sure if this is correct...)
(y-y1)=m(x-x1)
Given the point (10, 0) and a slope of m=1/2:
(y-10)=1/2(x)
Now, we must convert to slope-intercept form:
y=mx+b, where m=slope and b=y-intercept
Let’s transfer equation forms:
Add 10 to both sides:
y-10=1/2x
y=1/2x+10 is the answer

The variables x, y, z associated to the parallelogram are equal to 60, respectively.
How to find the measures of the variables associated to the angles of a parallelogram
A parallelogram is a quadrillateral formed by two pairs of parallel sides. The figure shows a parallelogram since the following relationships are met: BC ║ AD, AB ║ CD. We need three equations to determine the values of x, y and z and this can be obtained by means of parallelogram properties:
y = x
y + (x + y) = 180°
z + (x + y) = 180°
First, substitute x on the second and third equations:
3 · y = 180°
z + 2 · y = 180°
Second, find y:
y = 180° / 3
y = 60
Third, find z:
z = 180° - 2 · y
z = 180° - 2 · 60
z = 180° - 120°
z = 60
Fourth, find x:
x = 60
The values of variables x, y, z are 60, respectively.

The position of mailbox after 10s is equal to sum displacements is 14m.
The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
Given velocity time graph understand in three parts.

2. the mailbox at rest at 6-8 s.
the displacement covered by it s2=0
3. the mail returned with constant velocity 2m/s
Displacement is defined to be the change in position of an object. It can be defined mathematically with the following equation:
Displacement=Δx=[tex]x_{f} - x_{0}[/tex]

Applying the definition of the median of a triangle, the length of AO is calculated as: 14 units.
What is the Median of a Triangle?The median of a triangle is a line segment that joins the midpoint of a side of a triangle and the opposite vertex to the side.
There are three medians in a triangle, and the three of them intersect at a point inside the triangle. This point of intersection is known as the centroid.
According to the centroid theorem of a triangle, the length from the vertex to the centroid is two-third of the length of a median.
Thus, the figure shows that triangle ABC has three medians, BL, AM, and CK, which intersect at point O. This means the centroid of the triangle is point O.
By implication, it means that:
Length of AO = 2/3 * (length of AM)
Plug in the value of AM:
Length of AO = 2/3 * (21) [centroid theorem]
