A line passes through the point (–2, 4), and its y-intercept is (0, –6). What is the equation of the line that is perpendicular to the first line and passes through the point (5, –4)?

OpenStudy (anonymous):

do you know how to find the slope of the first line?

OpenStudy (anonymous):

I do not

OpenStudy (anonymous):

so slope equals the change in y coordinate divided by the change in x coordinate, or as some people say "rise over run" |dw:1451280431954:dw|

OpenStudy (anonymous):

can you calculate the slope of the first line using the two points that you are given?
