$slope = - 4$ $"slope "=-4$

Explanation:

$the equation of a line in slope-intercept form$ $"the equation of a line in "color(blue)"slope-intercept form"$ is.

$∙ x y = m x + b$ $•color(white)(x)y=mx+b$

$where m is the slope and b the y-intercept$ $"where m is the slope and b the y-intercept"$

$y = - 4 x + 9 is in this form$ $y=-4x+9" is in this form"$

$with slope m = - 4$ $"with slope m "=-4$

$m = - 4$ $m=-4$ .

Explanation:

We write it in the form of $y = m x + c$ $y=mx+c$ where $m$ $m$ is our slope.
Since, $y = - 4 x + 9$ $y=-4x+9$ is already in the form $y = m x + c$ $y=mx+c$ , we just compare these two.
We get, $m = - 4$ $m=-4$ .

Hope this helps :)
