So you have the find the slope of the line first, and the new line is have the same slope since they’re parallel. So to convert the equation to slope intercept form y=mx+b, the equation is now y=-x+3.
So the slope of new line is -1
Now plug in the point because the point is one the line.
-1=(-1)*(-1)+b
-1=1+b
2=b
So the new equation is y=-1x*2

Answer:

a = 3   b = 0

Step-by-step explanation:

(a,-2)   b= -2

-2=2a -8

6=2a

3=a

(4,b)   a=4

b=2(4)-8

Prove that the sum of ab and ba is divisible by the sum of a and b
Likurg_2 [28]

Answer:

It is divisible by 11 and (a + b) !

Step-by-step explanation:

Given a two digit number $ ab $, the digits written in reverse order is $ba $.

Note that a two digit number ab  = 10a + b.

For example: 24 = 10(2) + 4

Similarly, ba = 10(b) + a

Now, the sum of the numbers ab and ba = 10a + b + 10b + a

= 11a + 11b

= 11(a + b)

Hence, the sum of any two digit number ab and the reverse of the number ba,  is divisible by 11 and (a + b).

Hence, proved.
