Good work sir❤

Thanks a lot sir, more respect to you 🙏

[@CynthiaryNalisa]

On the y axis why we start counting on 5,10 ,15

[@GSCEMathematicsZone12]

We are conting in multiples of 5 because they said we draw the graph of the y - axis by using a scale of 2cm to represent 5 units.

[@shamadialawi1326]

But sir the box rep 1cm in y axis why 2ccm

[@EmeldahBbekumbe]

On x axis why didn't you go up to +4

[@GSCEMathematicsZone12]

Because in the question they said -4 ≤ x ≤ 2. Meaning that the x coordinates should start from -4 to +2 only.

[@blackfordbanda6553]

Am also on your question

[@blackfordbanda6553]

Sir you have made a mistake apo pa 0,4 you have indicated 0,8 why?

[@marthamakati-qj1yo]

The question was going on well but I think the sir made a mistake on the last part or it’s just me me seeing it🤔

[@GSCEMathematicsZone12]

Feel free to spot and mention the exact mistake you have discovered. It's possible to make mistakes as human beings. But I doubt if there is a mistake in this video.

[@inongelibongani1398]

Yes on -2,0 he made a mistake

[@robingoma]

​@@inongelibongani1398Oooh he said assume, it's negative 2. He didn't say that it was the exact or actual number which was supposed to be there.... The point was to see where the point will meet up with the curve

[@AliceMensah-r6q]

Please can you solve the questions

[@GSCEMathematicsZone12]

Noted, thank you.
Do you mean linear equations or quadratic equations?

[@ChrisKayenesha]

Yeah indeed the sir made a mistake on the last part of the question, the coordinates did not corresponding to the equation

[@GSCEMathematicsZone12]

Thanks for letting me know.

[@faisonflyg3724]

The presentation was on point but the problem was the question was not fully captured in the beginning, and after the solutions the answerd part again was not full captured for some seconds
Otherwise it's an excellent work keep it up and thank you you made my understanding easy 🫡

[@GSCEMathematicsZone12]

Thank you very much for the constructive comment. We really appreciate this and hope to work on the raised issues in the next videos. Thank you once again.

[@faisonflyg3724]

Otherwise you have really helped keep up the good works
