<u>Equation of a line</u>
A line can be completely defined by two points. Suppose we know the line passes through points A(x1,y1) and B(x2,y2).
The equation for a line can be written as:
Where m is the slope and b is the y-intercept. Both values can be determined by using the coordinates of the given points.
First, determine the slope with the equation:
The points are: A(15,3) B(3,15)
The equation of the line can be written as:
Now, use any point to determine the value of b. Substitute (15,3):
Solve for b:
b=18
The equation of the line is
y=-x+18
The slope is -1 and the y-intercept is 18.
