Find the slope of a line parallel to the line whose equation is 8, x, plus, 10, y, equals, 608x+10y=60. Fully simplify your answer.
To find the slope of a line parallel to the given line, we need to first rewrite the equation in slope-intercept form (y = mx + b), where m is the slope.
8x + 10y = 60
10y = -8x + 60
y = -0.8x + 6
The slope of the given line is -0.8.
Since parallel lines have the same slope, the slope of a line parallel to the given line is also -0.8.
Therefore, the slope of a line parallel to the given line is -0.8.
