Get in slope intercept form. 3X + 5Y = 15 5Y = -3X + 15 Y = -3/5X + 3 -3/5 is the slope of this line and the line parallel to this line
That depends what else is given, but basically you must find another line that has the same slope. For example, in y = 5x + 3, 5 is the slope; any other line with the same slope is parallel, for instance, y = 5x + 10, or y = 5x - 2.
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
If you mean: y=-5x+10 and the point (3, 10) then the parallel equation is y=-5x+25
The slope of any line parallel to another line is the slope of that line. In the form y = mx + c, the coefficient of x, ie the m, is the slope of the line. Thus any line parallel to y = 5x + 3 has slope 5.
Parallel lines have the same slope.
if you mean 3x + 4y = 8 the slope is -3/4 and any parallel line will have the same slope.
If you mean: 4x-2y = -3 then the slope of the line parallel to it will also have a slope of 2 but with a different y intercept
