$y=3x$

Work Step by Step

$\bf{\text{Solution Outline:}}$ Use the Slope-Intercept Form to find the equation of the line with the following characteristics: \begin{array}{l}\require{cancel} m=3 \\\text{Through: } (0,0) .\end{array} Express the answer in Slope-Intercept Form. $\bf{\text{Solution Details:}}$ The given point indicates that the $y$-intercept is $0$ or $b=0.$ Using $y=mx+b$ or the Slope-Intercept Form, the equation of the line is \begin{array}{l}\require{cancel} y=mx+b \\\\ y=3x+0 \\\\ y=3x .\end{array}
