Based on the examples given DURING OUR LESSON, what is the main difference between a Linear Equation and a Non-Linear Equation?

Exponent / Power

Standard Form

100

TRUE OR FALSE?

5x - 2y = 1 is NOT IN STANDARD FORM

False

200

write 7x = 4y + 1 in standard form

7x - 4y = 1

300

Write 6y = -5x - 10 in STANDARD FORM

5x + 6y = -10

400
