1+4=5 2+5=12. 3+6=21. 8+11=?

Answers

Hi there this is a puzzle question. So lets get to the answer. If 1+4=5 then we take 1+(4*1)=5. 2+5=12 so lets take 2+(5*2)=12. 3+6=21 so lets take 3+(6*3)=21. After all of this you should probably know now that I multiplied the first number with the second number then added both of the numbers. So, 8+11=8+(11*8)=8+88=96. Therefore, the answer is 96.

1What is the y-intercept of a line that has a slope of 2 and passes through point (8,3)?
1
3
5
11

Answers

First of all we need the line equation so let's find it first :

y = mx + b

y = 2x + b

_______________________________

The line passes through point ( 8 , 3 ) which means if put 8 instead of x the y must equals to 3 :

2(8) + b = 3

16 + b = 3

b = 3 - 16

b = - 13

______________________________

Now we have the equation of the line :

y=2x-13

To find the y-intercept we just need to out 0(zero)instead of x; Let's do it :

y = 2(0) - 13

y = 0 - 13

y = - 13

Thus the y-intercept=-13

Answer:

the y intercept is -13
