well all you need to do is find the slope as you know 2 points, one of which is an intercept the points are (0,3) and (a, a + 3) so the slope is m = (a + 3 - 3)/(a - 0) then you can substitute into the equation y = mx + b where m = slope of the line and b is the y-intercept
But this is an exponential problem
where does it say its an exponential equation... ?
ok... so the then for the exponential equation when x = 0 y = 3 as the intercept so the form is y = 3e^kx
