Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between
and
means that
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
or
,
which indicates a linear relationship between
and
because they are related by a constant.
Therefore, if x is doubled, then the new value of
is ![y_{new}](https://tex.z-dn.net/?f=y_%7Bnew%7D)
![y_{new}=c(2x)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3Dc%282x%29)
![y_{new}=2(cx)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2%28cx%29)
![y_{new}=2y](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2y)
The new value of
is 2 times the previous; therefore,
is doubled as
is doubled.
Hi!
Remember that an x-intercept is a point in which the line touches the x-axis (the horizontal line). And, the y-intercept is a point in which the line touches the y-axis (the vertical/up and down line)
-----------------
For A)
The coordinate of the y-intercept is (0,1)
The coordinate of the x-intercept is (3,0)
For B)
The coordinate of the y-intercept is (0,0)
The coordinate of the x-intercept is (0,0) !
*both the x and y axis meet at the origin. So, a line that goes through the origin (0,0) is intersecting with BOTH the x and y-axis.
Hope I helped! Comment if you have any questions or concerns.
