Drag equations to each row to show why the equation of a straight line is y = mx + b,
where m is the slope and b is the y-intercept.

  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.

a)(x-2)^2+(y-1)^2=9
