Which equation represents a linear function? (5 points) Equation 1: y3 = 2x + 1 Equation 2: y = 3x + 1 Equation 3: y = 5x2 − 1 Equation 4: y = 4x4 − 1 Equation 1 Equation 2 Equation 3 Equation 4

y = 3x + 1

Step-by-step explanation:

' y = 3x + 1 ' is a equation of a linear function. The equation is in slope-intercept form. All slope intercept-form lines are linear.

An equation for a linear function has no exponents, no variables in fractions, and no square roots.

Hope this helps.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
