Question

This is getting frustrating, can someone please help me? I'll fan and give a medal.

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (3, 2)

Answer 1

What is the slope of that given line (in the graph) ?

Answer 2

let me find it

Answer 3

the slope of the line is the change in y over the corresponding change in x
sometimes this is referred to as the rise/run
find 2 points on the given graph what is the slope?

Answer 4

when lines are perpendicular the product of the slopes is -1.
if one slope is m then the other slope is -1/m

Answer 5

now to find the equation of the line at a point use the slope intercept form
y = m x + b given (3, 2 ) and m (from above) we can calculate b
then write the equation for any (x,y)
