Describe a situation in which point-slope form would be more useful than slope-intercept form?

You use point-slope form to find the equation of a line if you only have a point and a slope or if you are just given two point. Usually you will convert point-slope form to slope-intercept form to make it easier to use.


Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point 1 1?

Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1).


How do you find point-slope form?

The point slope form of a line is one that contains the point and the slope. It is (y-y1)=m(x-x1) Where (x1,y1) are the point on the line that you are given. The other (x,y) are any x and y and m is the slope. So if we have a point (1,2) just for example, and a slope m=3, then the point slope equation or form is (y-2)=3(x-1) Note: The point slope form is easy to remember. It comes directly from the definition of slope. The slope is the rise over the run, of (change in y values) divided (change in x values) Now call the slope m, and let a point we know be (x1,y1) and any other point on the line (x,y), then the slope is m=(y-y1)/(x-x1). Now multiply both sides by (x-x1) and you have the point slope form.


Using the point slope formula what is the answer if the line pass through 0-9and-9-6?

Point-slope formula is y-y1=m(x-x1) The problem looks like: y-(-9)=-1/3(x-0) In Standard Form(answer): x+3y=-27


-2 -5 7 -6 in point slope form?

Point slope form of y-7=-3x identifies the line that pass through the slope of line (-2 -5) (7 -6).
