You can see it easily if you graph A(10,0) & B(20,0) on a on a system of perpendicular axis. The horizontal values (x value =10 & 20) are on the x axis & the vertical values (y value=0 & 0) can't be on the y axis since y values are zero
It is 19 why do people do this
Answer:
I believe that the answer is A
Step-by-step explanation:
Sorry if Im wrong but Im pretty sure Im right!
You have to evaluate the slopes of these lines. For line AB you have a slope of

For line CD you have a slope of

Because the slopes are equal and the two lines are not one and the same, they are parallel.
Step-by-step explanation:
To find the gradient:
y2-y1/x2-x1
Pick any two coordinates
11)
(4,3) and (1,-1)
-1-3= -4
1-4= -3
-4/-3 = 1.3(1dp)
12)
(0,1) and ( 2,-2)
-2-1= -3
2-0= 2
-3/2= -1.5
Might be wrong but this is what I got from what I have learnt.
Hope this helps! :)
