Question

If f(x) = 4x + 12 is graphed on a coordinate plane, what is the y-intercept of the graph? 4 8 12 16

Answer 1

$\bf \stackrel{~\hfill y-intercept}{f(x)=4x+\stackrel{\downarrow }{12}}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$

Answer 2

Answer:

The y-intercept would be 12.

Step-by-step explanation:

In the problem:

4x=slope

12=y-intercept
