Answer:
B. (-1,7)
C. (0,5)
D. (2,3)
Step-by-step explanation:
We solve this question looking at the graphic.
A. (-7, 1)
When , and thus (7,-1) is not solution of the equation.
B. (-1,7)
When , and thus (-1,7) is a solution of the equation.
C. (0,5)
When , and thus (0,5) is a solution of the equation.
D. (2,3)
When , and thus (2,3) is a solution of the equation.
E. (3, 2)
When , and thus (3,2) is not part of the solution
F. (5,0)
When , and thus (5,0) is not part of the solution

let's change the 3 into a mixed number with a denominator of 5:
-
=
so
is the answer
Answer:
0
Step-by-step explanation:
Since both points are on the the line (0,2) there is no slope/the slope is 0
Answer:
y=−1/5x+2
Step-by-step explanation:
First, you must find the midpoint of the segment, the formula for which is
(x1+x22,y1+y22)
. This gives (−5,3)
as the midpoint. This is the point at which the segment will be bisected.
Next, since we are finding a perpendicular bisector, we must determine what slope is perpendicular to that of the existing segment. To determine the segment's slope, we use the slope formula
y2−y1x2−x1
which gives us a slope of 5
Perpendicular lines have opposite and reciprocal slopes. The opposite reciprocal of
5 is −1/5
We now know that the perpendicular travels through the point (−5,3)
and has a slope of −1/5
Solve for the unknown b in y=mx+b
3=−1/5(−5)+b⇒3=1+b⇒2=b
Therefore, the equation of the perpendicular bisector is
y=−1/5x+2
The number (answer) is 2592.
