The equation of a line is given as y = -2/3x + 7/3
The formula for calculating the equation of a line is expressed as;
y = mx + b
where;
m is the slope
b is the y-intercept
Given the coordinate points (2, 1) and (-1, 3)
m = 3-1/-1-2
m = 2/-3
m = -2/3
Determine the y-intercept
1 = -2/3(2) + b
1= -4/3 +b
b = 1 + 4/3
b = 7/3
Hence the equation of a line is given as y = -2/3x + 7/3
