step 1

Find the slope of the linear equation

we take the points

(-1,-1) and (2,8)

so

m=(8+1)/(2+1)

m=9/3

m=3

step 2

Find the equation of the line in sloe intercept form

y=mx+b

we have

m=3

point (2,8)

substitute

8=3(2)+b

solve for b

8=6+b

b=2

the equation is

y=3x+2

and the value of b is 2
