Answer:
Point, Line, and Plane
Step-by-step explanation:
The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.
You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.
It is 3yd (the Hight) x 4 yard(half the base) = 12yard and that is actually double the size of the single triangle we just measured but add its partner back on its:

Answer:
y=-2/7x-4/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-(-2))/(-16-5)
m=(4+2)/(-21)
m=6/-21
m=-6/21
y-y1=m(x-x1)
y-(-2)=-6/21(x-5)
y+2=-6/21x+30/21
y=-6/21x+30/21-2
y=-6/21x+30/21-42/21
y=-6/21x-12/21
simplify
y=-2/7x-4/7
First add -2 and -6 together
Since these are both negitive signs you will add normally and and a negitive sign to the answer
-8
so you have...
-8 + 7
Since there is a negative (-8) and a positive (7) you will treat this as a normal subtraction problem, except your answer will have the sign of the biggest number
8 - 7 = 1
8 is the bigger number and has a negative sign therefore the answer is a negative number
so...
-8 + 7 = -1
-1
Hope this helped!
