Question

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

Answer 1

b

Explanation:

Answer 2

y = 3x + 1

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.
