0.3 Linear Equations and Inequalities

Question 1

linear equation

Answer 1

can be written in one of these forms:
- ax + b = 0

• ax + by + c = 0

Question 2

True or false?

If a problem includes an exponent or a root, it is a linear equation

Answer 2

False

Question 3

is x=0 a linear equation?

Answer 3

Yes. You can rewrite as ax + b = 0

1x + 0 =0

a=1 b=0

Question 4

Is y = 2x a linear equation?

Answer 4

Yes. You can rewrite as ax+b =0

2x-y = 0

a=2 b=-y

Question 5

Is x^2 + 5x – 6 = 0 a linear equation?

Answer 5

No, exponent

Question 6

Is x + y = 6 a linear equation?

Answer 6

Yes, you can rewrite as ax + by + c = 0

x+y-6 =0

a= 1 b = 1 c = -6
