The equation of the line given is 2 from the equation y = mx + b where m is the slope. For the lines to be parallel, their slopes should be equal. The equation of the line may also be expressed as,
y - y1 = m(x - x1)
Substituting the values,
y - 3 = 2(x - 5)
The simplified form of the equation is,
y = 2x - 7
