Answer:
yes, y=2x-3 is linear
2x - y = 3 Standard Form
Step-by-step explanation:
since both the 'x' and 'y' variables have one as their exponents then this represents a linear equation
standard form: Ax + By = C
y = 2x - 3
subtract 2x from each side to get:
-2x + y = -3
divide each term by -1 to get (this is done so the leading coefficient is not negative)
2x - y = 3 Standard Form
Your missing exponent would be 3
Use proportions and use letters for unknown measurements
