( 0, a) \displaystyle \left (0,a\right) (0, a), then a is the initial value. Using a, substitute the second point into the equation. f ( x) = a ( b) x. \displaystyle f\left (x\right)=a {\left (b\right)}^ {x} f (x) = a(b) . x. It is important to ensure we do not confuse the two-intercept form of the equation of a straight line with the standard form 𝑎 𝑥 + 𝑏 𝑦 = 𝑐. In the previous example, we had rearranged the equation of the line to give 2 𝑥 + 𝑦 = 6 at one stage in our working. This is not in two-intercept form as the constant on the right-hand side of the equation is not equal to 1.
