Question

What is the slope of a line perpendicular to the line in the graph?

Answer 1

To find the answer, we can use the slope formula:

$\frac{y1 - y2}{x1 - x2}$
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,-3) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,-3), while x2 and y2 would be the x and y coordinate in the second point (0,-1)

To find the answer, put any two points into the formula.

In this case, (1,-3) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,-3), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

$\frac{ -3 - ( - 1)}{ 1- 0} \\ = \frac{-3 + 2}{1} \\ = \frac{ -1}{1} \\ = -1$

Therefore the answer is -1.
