Or you can do the easy way
convert to slope intercept
y=mx+b
m=slope
get 1y all by itself
8x-4y=8
minus 8x both sides
-4y=-8x+8
divide both sides by -4
y=2x-2
y=mx+b
slope is 2
the hack way is
for an equatoin in standard form
ax+by=c
slope=-a/b
slope=2
if you want to graph 2 points and do it the long way, here it is
if x=0, y=-2
if y=0, x=1
(0,-2) and (1,0)
slope=(y2-y1)/(x2-x1)
slope=(0-(-2))/(1-0)=2/1=2
slope is 2
Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as 
then the equation relating them is
w = 
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w = 4 × 
= 4 × 2 = 8
w = 
← equation of variation
When x = 25, then
w = 
= 
= 1.6
