*Write the equation in slope-intercept form which is,
y = mx + b
First: add "x" to both sides...
- x + x - 4y = x - 32
- 4y = x - 32
Sec: isolate "y" on one side > divide each term by "-4"...
(-4y)/-4 = x/-4 - 32/-4
y = -x/4 - (-8)
y = - x/4 + 8
Third: the slope is a fraction/whole number beside the x-variable. in this case the slope is, (-1/4)

the slope is -1/4
-x - 4y = -32
-4y = x - 32
y = x/-4 = 8

When an equation is of this form:
-x - 4y = -32
we can reimagine it like this:
ax+by=c, where a, b, and c are constants
The slope will always be of this form:
-(a/b)
Hence, in the case of the equation above, a is -1, and b is -4:
-(-1/-4)=-(1/4)

if you put it in y = mx+b form, m is the slope
-x - 4y = -32
-4y = x -32
y = -1/4x +8
m = -1/4
slope = -1/4

-x-4y=-32
-4y=x-32
y=-x/4+8
Slope would be -1/4. Y-intercept would be (0,8)

-4y=-32+x
y= (32-x)/4
y= 8-x/4 (answer)
