first you must find the slope
y2-y1
------ = m =slope your points are 1=(2,3)and 2=(4,7) put these in the formula
x2-x1
7-3
--- = 4/2=2 your slope is 2
4-2
then you must use the point-slope equation y-y1=m(x-x1)
y-3=2(x-2)
y-2=2x-4
y=2x-2 this is y=mx+b form which is your slope intercept form

2,3,4,7
m=4/2=2
b=-1*m*x1+1*y1
b=-1*2*2+1*3=-1
y= 2x-1
