Answer:

a. Equation 1

Step-by-step explanation:

The slope-intercept form of an equation of a linear function:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

[tex]Equation\ 1:\ y=2x+1\qquad\boxed{YES}\\\\Equation\ 2:\ y^2=3x+1\qquad\boxed{NO}\ because\ we\ have\ y^2\\\\Equation\ 3:\ y=5x^5-1\qquad\boxed{NO}\ because\ we\ have\ x^5\\\\Equation\ 4:y=4x^4-1\qquad\boxed{NO}\ because\ we\ have\ x^4[/tex]
