#"slope "=-4#

Explanation:

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

#•color(white)(x)y=mx+b#

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

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

#"with slope m "=-4#

#m=-4#.

Explanation:

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

Hope this helps :)
