Junior Cert Maths Paper 2 - Coordinate Geometry Summary

A 15 minute summary of the main points in Coordinate Geometry from Junior Cert maths paper 2. Nice for quick exam revision. This video is not comprehensive and leaves out some of the more basic concepts.
Here are some more videos I recommend:

Rate of flow:

Difficult Quadratic equations:

Compound inequalities:

Simultaneous word problem:

Quadratic word problem:

Rearranging Formulae:

Coordinate geometry:

Trigonometry:

Sequences and Nth term:

Functions Exam Question:

You’re miles better at teaching than my maths teacher. You make everything much more straightforward. Thanks! This really helped.

Thank you for this! My maths teacher didn't teach me half of this stuff in class

0:01 positive and negative slopes

0:26 which formula to use (equation of the line)

1:47 find equation the line with *y = mx + c* if there is a diagram

3:01 find the equation of the line with
*y - y, = m (x - x, )* if there is no diagram

5:40 graphing lines

7:07 get the equation of lines parallel to axii

7:54 find the axis of symmetry of a quadratic function

8:14 parallel lines are always equal

8:54 prove that these 2 lines are perpendicular to each other

10:31 finding the y and x intercept

12:24 finding the point of intersection between 2 lines

13:20 is this point on the line?

Thanks for this. Great to see some Irish based videos when there are so many American ones out there. They are all great ways to revise.

thank you, very straight to the point and easy to wrap my head around!!

[Kob____]

Great video. Helped me a lot! Thanks so much :))

I have my mocks tomorrow thank you king xoxoxoxoxox

[joaogabi]

Can anyone tell me how he got x+y=2 without there being a two on the graph?

[isaacm]

wait a second at 8:01 isn't x only allowed to have one y value

[michaelmurphy]

At 9:20 the slopes are wrong. The line where it is, according to you a slope of 4/1 should be negative 4/1 and the line where you say it’s negative 1/4 should be a positive 1/4.

thx for helping me pass my test
got an A+
