Answer:
Graph 2 has a different constant of proportionality
Step-by-step explanation:
See attachment for graphs
To calculate the constant of proportionality, we simply determine the slope of each graph using
Where x's and y's are corresponding values of x and y
Graph 1:
Substitute these values in:
Graph 2:
Substitute these values in:
Graph 3:
Substitute these values in:
Graph 4:
Substitute these values in:
<em>From the calculations above, graph 2 has a different constant of proportionality of 5.5 while others have 5 as their constant of proportionality</em>
Answer:
The y-intercept is (0,210)
Step-by-step explanation:
We have the function,
So, we know that,
<em>'y-intercept is the point on the graph where the function crosses y-axis'.</em>
i.e. y-intercept is obtained when x=0.
Thus, substituting x=0 in the given function, we get,
i.e.
i.e.
i.e.
i.e. f(0) = 210
Also, we can see from the given graph that the function crosses y-axis at (0,210).
Hence, the y-intercept is (0,210).
