yfirst degree equation be solved for y, it may be compareddirectly with this slope equation. For example, given theequation 2 y — 3 x = 8. Solving for y, y = § x + 4; com-paring this with the typical form; m = § and b = 4. Hence the locus of 2 v — 3 x = 8 may be constructedas follows, remembering… … Fig. 16. (remembering that the angle must be measured from rightto left), the line DE, drawn through the points so deter-mined makes an angle whose tangent is f with the x-axis, OF for tan. FLO = 7^ = h hence any line drawn to ED makes the same angle. If this line is drawn through the 32 Analytical…
