If f(x) is an exponential function where f(2) = 14 and f(3.5) = 27, then find the
value of f(7), to the nearest hundredth.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
