Write the standard form of an equation of the line that passes through each pair of points:
In order to find the equation of a line, you need a point an a slope. You don't have a slope, but never fear, you have two points and can get the slope using the slope formula:
, where m=slope, and (x1,y1) and (x2,y2) are your given points.
(x1,y1)=(-5,7) and (x2,y2)=(0,1/2)
Now you have a point and a slope, so you can use the point slope formula to find the equation of the line:
, where m=slope and (x1,y1) is a given point.
(x1,y1)=(-5,7) and m=-13/10
The Standard form of a line is
, where A, B, and C are integers. A lot of books and teachers also require A to be positive.
