Answer:
y = 4x + 1 and y = −23x − 12
Step-by-step explanation:
A: y = 4x + 1 is a linear function; its graph is a straight line that passes through (0, 1) (the y-intercept).
B: is a quadratic (not linear) function; its graph is curved.
C: Are you trying to divide x + 1 by sqrt(3)? Unclear.
D: y = −23x − 12 also has the form of a linear function: y = mx + b
