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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

125 yards

step-by-step explanation:

i take 75 plus 50.
