What is the slope of a line perpendicular to the line in the graph? a. −3/2 b. −2/3 c. 3/2 d. 2/3

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


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)



Therefore the answer is -1.

Hope it helps!
