WebFor linear equations, we have y = m (slope) x + b (y intercept) and for exponential equations we have y = a (initial value)*r (ratio or base)^x. So in each case, we need to find two things. In both cases, the y intercept and initial value are found where x = 0 (y intercept) and the table gives us these, so linear b = 5 and exponential a = 3.
