42 : 2 = 21

21 : 3 = 7

7 : 7 = 1

42 = 2 · 3 · 7

15 : 3 = 5

5 : 5 = 1

15 = 3 · 5

GCF(42, 15) = 3

Find the slope of the line 8x – 4y = 8\ (hint: find 2 points; then use the slope formula)
vodka [1.7K]
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
