The graph of a proportional relationship passes through(6, 42)
and (1, y). Find y.
Thanks
To find the value of y, we need to determine the constant of proportionality (k) first. In a proportional relationship, the ratio between the y-values and x-values of any two points on the graph should be the same.
We can use the given points (6, 42) and (1, y) to set up an equation:
k = y / x
Using the coordinates of the first point (6, 42), we have:
k = 42 / 6
Simplifying this expression, we get:
k = 7
Now that we have determined the value of k, we can find the value of y by substituting it into the equation:
7 = y / 1
Multiplying both sides of the equation by 1, we get:
7 = y
Therefore, the value of y is 7.
So, y = 7.
42/6 = Y/1.
Y = 7.
let y = kx , (your proportional relationship)
Plug in the point (6,42)
42 = 6k
k = 7
so y = 7x
for (1,y) you are missing the y
y = 7(1) =
