Question

mrs.jackson gives the table below to her students in order for the function to be linear what must m be and why?​

Answer 1

M or the slope has to be constant throughout the graph. This is because in order for a line to be linear it has to be increasing or decreasing at the same rate. So it the slope was 2 from point x 1 -2 then the slope changed to 1 from 3-4 it would not be linear. :)
