Calculate the equation of line that passes through the points (-32,-14) and (13,21). (Hint: Use point-slope form for the equation of the line)

OpenStudy (anonymous):

Do you know the point slope formula?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

Ok, so do you know the formula for the slope of a line passing through two points?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

Ok, so if you have two points. The slope of the line passing through them is: $Slope = {y_2-y_1 \over x_2-x_1}$ Where $$(x_1,y_1)\text{ and }(x_2,y_2)$$ are your two points.

OpenStudy (anonymous):

so i just have to plug in the x and y values. right?

OpenStudy (anonymous):

Yes. That will give you the slope. Then just pick one point and use that slope with the point you chose in the point-slope formula.

ok... thanx
