✔ 最佳答案
y = ax + ba is the slope!
4x-2y=8
-2y = -8 - 4x
y = 4 + 2x
slope = 2

First, you need to set this equation as y equal to (in the slope form y=mx+b). So you have:
y = 2x-4
Now remember that m is the slope
Therefore, the slope of this equation is 2.
y = 2x-4
Now remember that m is the slope
Therefore, the slope of this equation is 2.

4x - 2y = 8
-2y = 8 - 4x
y = (8 - 4x)/-2
y = -4 + 2x
y = 2x - 4
Slope: 2
-2y = 8 - 4x
y = (8 - 4x)/-2
y = -4 + 2x
y = 2x - 4
Slope: 2

from inspection the slope is 2,
put the equation in point slope form
y=mx + b
where M is the slope.
put the equation in point slope form
y=mx + b
where M is the slope.

change the equation to y= mx + c which are m= slope and c= y-intercept
4x-2y=8
-2y=8-4x
y=(8-4x)/ -2
y= -4+2x
y=2x-4
so, the slope is 2
4x-2y=8
-2y=8-4x
y=(8-4x)/ -2
y= -4+2x
y=2x-4
so, the slope is 2

2y = 4x - 8
y = 2x - 4
Slope , m = 2
y = 2x - 4
Slope , m = 2

Forgetting the formula will lead you to this.
Slope of ax+by +c =0 is - a/b
Slope of ax+by +c =0 is - a/b

Slope of the line = -coefficient of X / coefficient of Y= -4/(-2) = 2

Write in slope intercept form:
-2y = 8 - 4x
-y = 4 - 2x
y = 2x - 4
The slope is 2.
Or just do -a/b in standard form for -4/-2 = 2
-2y = 8 - 4x
-y = 4 - 2x
y = 2x - 4
The slope is 2.
Or just do -a/b in standard form for -4/-2 = 2
