Question

A table contains the ordered pairs (3, 42.25) and (5, 50.75). If the relationship in the table is linear, explain how to find the initial value.

Answer 1

you'll need to plug in both points into the slope formula to find the rate of change

from there, you'll need to set up y = mx + b, plug in one of the x,y values, then plug in m, then solve for b. since b is the y-intercept (the value when x = 0), then b is also your initial value
