Nancy wants to make a graph to show the relationship between the temperature of water, in degrees celsius, and the time, in minutes, for which water is heated. she plots the following points:
(0, 50), (1, 60), (2, 70), (3, 80), (4, 90)
she uses the following steps to plot the graph:
1) label origin as (0, 0)
2) on x-axis, label time in minutes.
3) on y-axis, label temperature in degrees celsius.
4) the scale on x-axis starts from 0 and goes up to 5 at intervals of 1.
5) the scale on the y-axis starts from 0 and goes up to 200 at intervals of 50.
which of the following best describes the graph?
a) it will not be spread out horizontally across the entire coordinate plane because in step 4, nancy selected an incorrect scale on the x-axis.
b) it will not be spread out vertically across the entire coordinate plane because in step 5, nancy selected an incorrect scale on the y-axis.
c) it will not be spread out horizontally across the entire coordinate plane because in step 2, nancy plotted time instead of temperature on the x-axis.
d) it will not be spread out vertically across the entire coordinate plane because in step 3, nancy plotted temperature instead of time on the y-axis.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
