One way is to make into fracitons and simplify
A.5/7=25/35?
yes, true
B. 6/9=18/36?
no
C. 9/18=16/36?
no
D. 35/120=75/250?
no
another way is
if a/b=c/d, then (ad)/(bc)=1 or ad=bc
A is answer
Slope intercept form is y=m(x)+b
M is the slope to find it you do the first y value minus the second y value and do the same for x
-6-2. 3+1
You then divide the subtracted y values by the subtracted x values
-8/4
M=-2
To find the b you plug in one set of the coordinates
-6=-2(3)+b
-6=-6+b
b=0
So the equation is
Y=-2x
Answer:
20
Step-by-step explanation:
20-6=20
1. y= 6
2. y= 12
3. y=18
4. y= 24
5. y=5
6. y= 10
7. y=15
8. y= 20
9. y=0
10. y= 0.2
11. y=0.4
12. y=0.6
Hope this helps!
