የሊኒያር እኩልዮሽ ስዕል ሰንጠረዥ
ሊኒያር ተብሎ የሚታወቀው የሂሳብ እኩልዮሽ ይህን ይመስላል፦
![{\displaystyle y=mx+b,\,}](https://wikimedia.org/api/rest_v1/media/math/render/svg/aaa51187dea311bf200c4450dfa88d499efeb8d6)
yና"x" ተለዋዋጭ ዋጋ ሲወክሉ m ና b, ደግሞ ቋሚ ዋጋን ይወክላሉ።
እኩልዮሹ በተለያየ መንገድ ሊጻፍ ይቻላል፣ ለምሳሌ፦
![{\displaystyle Ax+By+C=0,\,}](https://wikimedia.org/api/rest_v1/media/math/render/svg/bb8281169914e5543dc99afc80da0753781abd7a)
