Determine the intercepts of the line that correspond to the following table of values.
1 answer:
We know that
to find the equation of a line i need two points
let
point A-----> (-21,10)
point B-----> (-28,14)
step 1
find the slope m
m=(y2-y1)/(x2-x1)-----> m=(14-10)/(-28+21)----> m=-4/7
step 2
find the equation of a line with
m=-4/7 and the point A (-21,10)
y-y1=m*(x-x1)------> y-10=(-4/7)*(x+21)---> y=(-4/7)x-12+10
y=(-4/7)x-2
step 3
find x intercept
for y=0
y=(-4/7)x-2------> 0=(-4/7)x-2-----> 4/7x=-2----> x=-14/4----> x=-3.5
the x intercept is (-3.5,0)
step 4
find the y intercept
for x=0
y=(-4/7)x-2--------> y=-2
the y intercept is (0,-2)
the answers are
the x intercept is (-3.5,0)
the y intercept is (0,-2)
see the attached figure

Answer:
Step-by-step explanation:
Given
below sea level
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
Required
Determine the elevation of the Sea of Galilee
We have that the lowest elevation in Lammefjord is:
It is negative because, the elevation is below sea level.
Calculating the elevation of Sea of Galilee, we have:
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>
