Which is a Linear Equation? A. Y=3-2x B. Y= -7x^2 C. Y=2-3x^2 D. Y=-7×^3
2 answers:
Answer:
(A)
Step-by-step explanation:
A linear equation can be written in slope intercept form, .
X must be in it's first power in a linear equation. X being in any other power will result in a curved line.
This eliminates B, C and D already. X is not in it's first power in the given three options.
The best option is A.
