Exponential Function From Semi-Log Plot

Mark

An exponential function is defined by $y = ab^x$ . When $\ln(y)$ is plotted against $x$ , the resulting graph is a line with a slope of 0.3 and a y-intercept of 2.5. What are the values of $a$ and $b$ ?

$a = e^{0.3}, b = e^{2.5}$

$a = 2.5, b = e^{0.3}$

$a = 2.5, b = 0.3$

$a = e^{2.5}, b = e^{0.3}$
