How do you find an equation of the straight line passing through the points with coordinates (-1,5) and (4,-2), giving your answer in the form ax+by+c=0?
Please see the explanation for details regarding how one does the requested process.
The definition of the slope, m, of the line between two points,
Using the given points to compute m:
The slope-intercept form of the equation of a line is:
Using the slope and the point
b = 18/5
The slope-intercept form of the line that goes through the two given points is:
But we want the form,
