Going to need help with a bit more of these.. thanks brainly :)

Answer: -6
Step-by-step explanation:
ok so basically rate of change = slope or m
so take two set of points from the table and do the slope equation which is y2- y1 over x2 - x1 (i can't really do equations in brainly bc i'm new so sorry but u can search up the equation)
so in this case, let's do the points (3, -15) & (4, -21)
now let's plug those values into the equation
so - 21 + 15 = -6 and 4 - 3 = 1
now u would simplify or divide so -6 divided by 1 = -6 so that's it! hope this helps!
