Question 995328: It says "Write in standard form the equation of each line", and there's just this one that I'm stuck on...: slope = -3/5; (-4, 0)
The answer options are:
a) 5x + 3y = -12
b) 3x + 5y = -12
c) -3x - 5y = 12
d) 5x -3y = 12

You can put this solution on YOUR website!
the standard form of the equation for a line is y = mx +b, where m is the slope and b is the y intercept
*******************************************************************************
we are given m = -3/5 and point (-4, 0)
y = (-3/5)x + b
multiply both sides of = by 5
5y = -3x + 5b
use point (-4, 0)
0 = 12 +5b
b = -12/5
equation for your line is
y = (-3/5)x - 12/5
multiply both sides of = by 5
5y = -3x -12
**************************************************
3x +5y = -12
answer is b.
