If y is equal to 17 when x is equal to a, and the relationship between x and y is described by the equation y = mx, then we can substitute these values into the equation to find the value of m:
y = mx 17 = m \* a
To find the value of y when x is equal to 2a, we can substitute these values into the equation:
y = mx y = m \* (2a)
So the value of y when x is equal to 2a is equal to m times 2a. The value of m can be found by solving the equation 17 = m \* a.
