Answer:
change in y / change in x
Step-by-step explanation:
rise = change in y
run = change in x
Answer:
x = 60
Step-by-step explanation:
X/2-5=25
Add 5 to each side
X/2-5+5=25+5
x/2 = 30
Multiply each side by 2
x/2*2 = 30*2
x = 60
Hey there!
First, find the slope of the actual original pair of points.
The slope formula is:
So now, substitute the points in, whichever order you substitute the points into the equation doesn't matter, as long as the ones substituted in with the same subscript number.
\
Once you subtract, you get:
So the slope is 11/10.
A line that is parallel to another has the exact same slope that that another line has.
So therefore the line that is
parallel has a slope of 11/10.
Perpendicular is another story. You take the reciprocal of the slope of the other line, and then change the sign before it: ex: negative would become positive.
So therefore the line that is
perpendicular has a slope of -10/11.
Answer:
Triangles OAB,BOC,COD,DOA are isocele and right , are thus equals and have the same hypothenus . The quadrilater ABCD is a diamond (having 4 sides equals) and its diagonals perpendicular is thus a square.
