Question

Find the distance between a point (–7, –19) and a horizontal line at y = 3. Choices are in the attachment...

Answer 1

What measurement unit do you want it in? and on a graph?

Answer 2

Answer: A) 22

Explanation:

The distance we're after is the vertical distance from the point to the line. So we only care about the difference in y values from y = -19 to y = 3

You can count out the spaces or use subtraction along with absolute value

distance from P to Q = |P-Q|

distance from -19 to 3 = |-19-3|

distance from -19 to 3 = |-22|

distance from -19 to 3 = 22

The absolute value is to ensure the result is never negative.
