Answer:
w = 2t + 10
Step-by-step explanation:
in this equation, t is your independent variable [x], and w is your dependent variable [y]
we know when writing a linear equation, the slope-intercept [most common] form is y = mx + b; where m is the slope [rate of change] and b is the y-intercept [initial value]
so, weight equals increase in pounds per month plus the baby's original weight
from this, you get W = 2t + 10
