Answer:
An equation is linear if its graph forms a straight line. This will happen when the highest power of x is 1. Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola, or any other conic for that matter it is a quadratic or nonlinear equation.
Answer:
true
Step-by-step explanation:
-12/-9=y/-4
cross multiply
-9y=48
divide by 9 on each side
y= -5.33
X-x-2/6=x-7/3+2/3
-2/6+7/3-2/3=x
x= -2/6+5/3
x= 8/6
x= 4/3
