Firstly, find the slope using the equation m=y2y1x2x1. m is a slope, (x1,y1) and (x2,y2) are two points on the line.
For example,
If we have points (2;1) and (4;3)
m=3(1)4(2)=46=23
Now, determine the point-slope form of a linear equation (yy1)=m(xx1), where (x1;y1) is one of the points
Use our example,
(y(1))=23(x(2))=
(y+1)=23(x+2)
Convert it into the slope-intercept form y=mx+b, where m is a slope and b is the y-interxept, by solving for y.
y+1=23x+2
y=23x+1
Thus, the slope intercept is 1
