Question 249529: trying to find slope and y integer for this problem -3x -5y = -25 please help also need to know the parallel slope and perpendicular slope Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! Work the algebra to get the equation into slope-intercept form: y = mx + b.
-3x -5y = -25
.
Add 3x to both sides
-5y = 3x -25
.
Divide both sides by -5.
y = -3/5x + 5
.
Slope is -3/5 so any line with slope -3/5 will be parallel.
y = -3/5x for example.
.
Any perpendicular will have negative inverse slope: 5/3.
y = 5/3x for example
.
The following graph illustrates:
red line: y=-3/5x+5
green line: y=-3/5x
blue line: y = 5/3x
.
