Question

Find the equation of the line that passes through (-2,5) and is perpendicular to the line passing through (-6,1/2) and (-4,2/3). Write the equation in slope intercept form.

Answer 1

let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmmmm what's the slope of the line through (-6,1/2) and (-4,2/3) anyway?

so we're really looking for the equation of a line whose slope is -12 and runs through -2,5.
