Hi,
*Note: Slope can be detemined by using the point-slope formula
.
(–1, 2) and (2, –3)
.
.
using the equation of a line y= mx + b where m is the slope and b the y-intercept
.
substituting one of the points (-1,2) to solve for b
b= 1/3
.
equation of the line:
y = (-5/3)x + 1/3
which may be written as
3y + 5x = 1
.
Might recommend substituting the Points given (–1, 2) and (2, –3) to check your answer
