-5x-4y = 6
-4y = 5x+6
Divide all terms by -4
y = -1.25x-1.5
Slope = -1.25 and intercept = -1.5

To answer this question we need to first get the slope of the line 5x-4y=9 by rearranging it in the form of y=mx+b: 5x-4y=9 4y=5x-9 y=(5/4)x-9/4 Since the slope of parallel lines are negative reciprocals of each other, the negative reciprocal of 5/4 is -4/5, therefore the slope of a line parallel to the line 5x-4y=9 is -4/5
Point Slope Form - Y=.5X+1.5
Transform the equation into slope-intercept form: y = mx + b. The intercept is b. 5x - 4y = 18 -4y = 18 - 5x 4y = 5x - 18 y = 5x/4 - 18/4 so the y-intercept is -18/4 or -4.5
If: y = 2/5x+10 then the perpendicular slope is -5/2x or -2.5x
