Question

What’s the slope of a line passing through (-5,-5) and (1,-3)

Answer 1

Write the equation for the vertical line passing through (-5 , 2 ) Any vertical line has the equation x = k, where k is the x-coordinate of any point the line goes through . x = - 5 .

Explanation:

Step One: Identify two points on the line .

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

Step Three: Use the slope equation to calculate slope .
