Answer: The first table has a slope of 5 and y-intercept of 20
Step-by-step explanation: You can find the y-intercept by looking for when X=0. When X=0 the y point would be the y intercept. In this case it is (0, 20).
You can find the slope by doing the change in y divided by the change in x. For this the change in y would be 60 and the change in x would be 12. This leaves 60/12 which is 5.
Answer:First, you must find the midpoint of the segment, the formula for which is
(
x
1
+
x

,
y

+
y

)
. This gives
(

,
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
y

, which gives us a slope of

.
Perpendicular lines have opposite and reciprocal slopes. The opposite reciprocal of
5
is
−

We now know that the perpendicular travels through the point
(

and has a slope of

Solve for the unknown

Therefore, the equation of the perpendicular bisector is
