Question

Which ordered pair is not included in a graph of y= 2 x + 5

Mimi chose A (0,0) how did she get that answer? and is she correct.

Answer 1

Mimi got that answer from looking at the constant of the equation: 5. The 5 represents the y-intercept, or in other words, the point at which the line on a graph touches the y-axis.

Mimi is correct because according to the y-intercept of (0,5), the line does not go through the origin and will never touch the point (0,0).
