Question

Identify the slope of the line for the equation y = −8x + 1.

A) −8
B) −1
C) 1
D) 8

Answer 1

`\bf y = \stackrel{\stackrel{m}{\downarrow }}{-8}x+1\qquad \impliedby \begin{array} \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

A

Explanation:

the slope formula is y=mx+b the slope being mx so m is the slope
