Does the following relation represent a function?

             (9, -6), (9, -5), (4, -1), (1, -4)

no, each INPUT must have exactly ONE output

Write the Slope-Intercept form equation
Y = mx + b
100

What is the y-intercept of this equation?

                     y = 4x +1

What is positive 1?
200

Does the following relation represent a function?

  (9, -6), (7, 5), (4, -1), (4, -4)

WHY or WHY NOT?

No, because each input must ONLY result in ONE output (4 is repeated in the INPUT)
