Math Paper 2

[Aitch Dee]

My Math paper 2 IG is tomorrow and I've got a bunch of questions. For example: How do you solve question 6 a in ON 12? Also, how do you find the equation of a line, the equation of a line parallel to another line, and the equation of a line perpendicular to another line? If anyone could help, I'd appreciate it.

Here these notes have answers to all ur doubts

 

[Mariam879]

and which varient for your question is it ON12 v1 or v2?

 

[Mariam879]

When wanting to find the range you subtract the largest number which is 5 and smallest 1 , so its 5-1=4

 

[Aitch Dee]

Thank you! It's paper 22. The largest and smallest number from the frequency?

 

[Mariam879]

from the number of people

 

[Aitch Dee]

Oh, thanks again!

To find equation of a line: You need: Gradient(Slope) and y-intercept. Y=mx + b m=Slope and b= y-intercept.
To find equations of parallel lines: They have the same slope.
To find equations of perpendicular lines: You use the given slope, and use this formula: -1/m

THE GRADIENTS OF PERPENDICULAR LINES ADD UP TO -1

 

[Aitch Dee]

Thank you all.

THE GRADIENTS OF PERPENDICULAR LINES ADD UP TO -1

No, they multiply to give -1.

Perpendicular gradients are not part of the IGCSE syllabus.
