Answer:
-5.6
Step-by-step explanation:
first distribute the 2.5
also convert the 2/5 to decimal (0.4) because it's hard to work with both decimal and fraction
2.5y + 2.5*0.4 = -13
2.5y +1 = -13
y = -14/2.5 = -5.6
4x is the proportionality
Answer:
1. y = -0.6x + 5.4.
2. The entered points belong to a vertical line. There is no slope.
Equation: x = 6
3. y = 0.16667x + 5.5.
4. The entered points belong to a vertical line. There is no slope.
Equation: x = -8.
Step-by-step explanation:
X<20-5y (the whole expression divided by 3)
