Answer:
AB = 16 units
Step-by-step explanation:
Given the coordinate (-4, 9) and (-4, -7)
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
AB =√(-7-9)²+(-4+4)²
AB = √(-16)²+0²
AB = √16²
Hence the distance between Point A and Point B is 16 units

t = -18, 18
Take the square root of both sides of the equation.
... t = ±√324 = ±18
