You can put this solution on YOUR website!
recall:
Alinear function is a function whose graph produces a line. Linear functions can always be written in the form
y=ax%2Bb ory=b%2Bax( they’re equivalent)
where bis the initial or starting value of the function (when inputx=+0, it's y-intercept) and a is the constant+rate+of change of the function.
you are given:
rate of change 3 which means a=3
and initial value -1 which means b=-1
so, you have y=3x-1
