What is the gradient of the blue line?

.25 or 1/4

Step-by-step explanation:

to find gradient/ slope,

choose any two points on line and divide the difference in y- values over difference in x- values

i.e. (0, 1), (10, 3.5)

2.5/10=.25 or 1/4

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
