$\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{-6})~\hspace{10em} slope = m\implies 5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-6)=5[x-(-4)] \\\\\\ y+6=5(x+4)\implies y+6=5x+4\implies y=5x-2$

Step-by-step explanation:

<u>Properties used</u>

logₐ a = 1
log aᵇ = b log a
log ab = log a + log b

See the steps below

- (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- (0.6 - 3*log 10) =
- (0.6 - 3*1) =
- (0.6 - 3) =
- (- 2.4) =
