Question

A linear function has a slope of 5 and crosses the y-axis at -12 what is the equation of the line​

please answer

Answer 1

if it crosses the y-axis as -12, that means that's its y-intercept, and we know its slope.

`\begin{array}c \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}~~ \implies ~~y=\stackrel{\stackrel{m}{\downarrow }}{5}x\underset{\underset{b}{\uparrow }}{-12}`
