Find an equation of the line with the given points Express a

Find an equation of the line with the given points. Express answer in x=a, y=b, or y=mx+b

(-1, 1) (5, 5)

points are ( -1 , 1 ) and ( 5,5)

finding slope of the line

m = y2 - y1 / x2 - x1

m = 5 -1 / 5 +1 = 4 / 6 = 2/3

standard equation is given by

y = mx + b

taking any one point and plugging the values

5 = 2/3 ( 5) + b

5 = 10/3 + b

b = 5 - 10/3 = 5/3

hence, equation of line is

y = 2/3 x + 5/3
