Answer:
y = 16 and y = -3x + 10
Step-by-step explanation:
The equation of a linear function:
y = mx + b
m - slope
b - y-intercept
x = 3 - it's a vertical line. It's not equation of a linear function
y = 16 - it's a horizontal line. It's an equation of a linear function
where m = 0, b = 16
y = -3x + 10 - it's an equation of a linear function
where m = -3, b = 10
y = 3x² + 1 - it's a quadratic function ( x² ).
