SOLUTION: here is the what the question asks. Find the slope of the line perpendicular to the following line, now it shows a graph with a line going through the middle and the top point

Question 717216: here is the what the question asks.
Find the slope of the line perpendicular to the following line,
now it shows a graph with a line going through the middle and the top point says (-2,1) and the lower point says (2,-1). please help thanks

the slope of the lines are negative reciprocals to each other
if is the slope of the line, the line perpendicular to the that line will have the slope
you first need to find the equation of the line going through the (-2,1) and (2,-1) and find its slope

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (-2, 1) and (x2, y2) = (2, -1).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-0.5)x + (0)

Your graph:

so, the slope
then the line perpendicular to the that line will have the slope
that line could be
