b

=

1

Now that the values of  

m

(slope) and  

b

(y-intercept) are known, substitute them into  

y

=

m

x

+

b

to find the equation of the line.

y

=

1

Answer 2

Answer:

y=5/4x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-1)/(0-4)

m=-5/-4

m=5/4

y-y1=m(x-x1)

y-1=5/4(x-4)

y=5/4x-20/4+1

y=5/4x-5+1

y=5/4x-4
