one solution
Step-by-step explanation:
y = 3/4x - 5
3x+ 4 y= -20
Substitute the first equation into the second equation
3x+ 4 (3/4x -5)= -20
Distribute
3x +3x - 20 = -20
6x -20 = -20
Add 20 to each side
6x -20+20 = -20+20
6x = 0
x=0
We need to find y
y = 3/4x -5
y =0-5
y = -5
There is one solution
A) one
3x + 4(3x/4 - 5) = -20
3x + 3x - 20 = -20
x = 0
One solution: (0,-5)
slope = (y2 -y1) ÷ (x2 -x1)
slope = (0 -0) / (-5, -7)
slope = 0 / -12 = 0
the slope of the line is zero. it is perfectly horizontal.
