Parallel lines has equal slopes.
Equation of the line 2x + y + 1 = 0 in slope intercept form is y = -2x - 1 with slope of -2. Therefore, the slope is -2.
Answer:
96 one bedroom homes
64 two bedroom homes
32 three bedroom homes
Step-by-step explanation:
If x is the number of 1 bedroom homes, y is the number of 2 bedroom homes, and z is the number of 3 bedroom homes:
x + y + z = 192
x = y + z
x = 3z
Solve the system of equations using substitution or elimination. Using substitution:
x + x = 192
2x = 192
x = 96
z = x / 3
z = 32
y = x − z
y = 64
