ok so we know slope intecept form is y = mx+c so...
2y+20x11=16x+12
i am not sure if thats 20x times 11 or 20 times eleven so il multiplication:
2y=16x+12 - (20 multiply by eleven) we transferr this to lfet side
2y=16x+12 - 220
2y=16x - 208 divide whole thing by 2 to get y instead of y 2
y = 8x - 104
Comment if u meant something different so il do another case too :) good luck
