Answer:
m=

Step-by-step explanation:
Slope of a line is the co efficient of x in the given line.

Answer: y = 1.8
Step-by-step explanation:
xy = 12.6 If x is 7 but 7 in the equation for x
7y = 12.6 Divide both sides by 7
y = 1.8
5(2y-4) - 3y = 1. 10y-20-3y=1. 7y-20=1. 7y=21. y =3. x = 2(3)-4. x = 2. x*y =6.
Option 2 => 6.4^2
Because area of a square = side *side or side^2
