What is the linear equation obtained by rotating the root of the line three X-Y + 1 = 0 around the point (0,1) by 30

What is the linear equation obtained by rotating the root of the line three X-Y + 1 = 0 around the point (0,1) by 30

The slope of √ 3x-y + 1 = 0 = √ 3 let the slope of the straight line be K. from the included angle formula, Tan 30 ° = | K - √ 3 | / | 1 + √ 3K | = √ 3 / 3 simultaneous square (k - √ 3) & # 178; / (1 + √ 3K) & # 178; = 1 / 33 (K & # 178; - 2 √ 3K + 3) = 1 + 2 √ 3K + 3K & # 178; 8 √ 3K = 8K = √ 3 / 3 √ linear equation Y-1 = √ 3 / 3x, that is y = (...)
