Question 394144
If y=2x-3 is graphed on {x: -2 <u><</u> x <u><</u> 5}, what are the coordinates of the right endpoint of the graph? (Show Your Solution)

<pre>

Since {x: -2 <u><</u> x <u><</u> 5}, we find the right endpoint by
substituting the largest possible value x can have for x, which is 5
into the equation

y = 2x - 3

for x, getting

y = 2(5) - 3
y = 10 - 3
y = 7

and using that largest value of 5 for the x-coordinate and the 7 that
you got for y for the y-coordinate.  So it's (5,7).

{{{drawing(400,400,-10,10,-10,10, graph(400,400,-10,10,-10,10),

line(-2,-7, 5,7), circle(-2,-7,.1), circle(5,7,.1),circle(-2,-7,.15),
circle(5,7,.15), locate(5,7.5,"(5,7)"), locate(-5,-7,"(-2,-7)") )}}}

Answer: The endpoint on the right is the point (5,7) as you see on the
above graph.
