Answer:
2k
Step-by-step explanation:
Let k is the ratio between two variables or y = kx
when x double, means: y = k (2x) = 2kx quantity y will change with a ratio 2k
Answer:
Option B
y coordinate is 0
Step-by-step explanation:
We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.
X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0
To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.
Thus we have along x axis, y values to be 0
Hence any point on x coordinate will be of the form (a,0) where a can be any real number
So option B is right
Answer:
Y= 1/3x + 4
Step-by-step explanation:
4 is the y intercept and it goes across one and down 3 for the get the slope of 1/3.
Answer:
10 %
Step-by-step explanation:
We first find change in the quantities
Then we write the change in quantity on original quantity and multiply by 100%
This implies that,



Therefore the percentage increase is 10%
