#"slope "=2" y-intercept "=-6#

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"#

#"rearrange "8x-4y=24" into this form"#

#"subtract "8x" from both sides"#

#-4y=-8x+24#

#"divide all terms by "-4#

#y=2x-6larrcolor(blue)"in slope-intercept form"#

#"with slope "=2" and y-intercept "=-6#

Slope: #2#
#y#-int: #-6#

Explanation:

We can easily find the slope and #y#-intercept of this line by converting it to slope intercept form

#y=mx+b#, with slope #m# and a #y#-intercept of #b#.

Let's subtract #8x# from both sides to get

#-4y=-8x+24#

Next, we divide all terms by #-4# to get

#y=2x-6#

Now that our equation is in this form, we see that our slope is #2#, and our #y#-intercept is #-6#.

Hope this helps!
