There are many different ways of representing the equation of a line. With the given information, the best form of the equation to use is point-slope form which can be written as
where
is the x and y coordinates of a given point on the line and
is the slope of the line. Since you are given that the slope of the line is 3 and has the point (-1,-8), the equation should look like
, which is letter choice D.
Okay, let me first explain what the equation<em> y = 8.77x + 686 </em>means
<em>y </em><em>is the hikers elevation </em>
Look at the graph and see what the y and x axis's are labeled as.
<em>x </em><em>is time. </em>
8.77 is just the slop of the trend line.
<em>686 </em><em>is just the elevation the hiker starts at</em>, or in technical terms, the y intercept. Y intercept is just where the lines touches the y axis.
The question asks what will be the <u>hiker's elevation at 145 minutes. </u>
To solve, just simply <u>plug in 145 as X </u>in the equation above. Remember x is time.
It will look like this :
y = 8.77 (145) + 686
Then solve.
y = 1271.65 + 686
y = 1957.65
Reminder: They want the nearest whole number!
Round 1957.65 feet to 1958 feet

F(x) = x2+2x-3 = 1
g(x) = x2-9 = -7
(f/g)(4) = (1/-7)(4) = (-0.14)(4) = -0.57
(f+g)(4) = (1+(-7))(4) = (-6)(4) = -24
The intersection of the perpendicular bisector of GF and the angle bisector of ZE inside the quadrilateral.
What is a quadrilateral?
quadrilateral is a plane mathematical closed figure consist of four side and four edges. There are 7 types of quadrilateral
a) Trapezium,
b) Parallelogram,
c) Rectangle,
d) Rhombus,
e) Square,
f) Kite
as the given figure is unknown with dimension it is difficult to find the measurement but it is be to noted that the perpendicular bisector of GF and angle bisector of angle E will intersect at some point inside the given quadrilateral.
