Find the slope of the line graphed

2/5

Step-by-step explanation:

We have two points so we can find the slope using

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

(-1,-1) and (4,1)

  m = (1 - -1)/(4 - -1)

      = (1+1)/ (4+1)

      = 2/5

2/5

Step-by-step explanation:

slope of a graph=

so the difference of y=1-(-1)=1+1=2

so the difference of x=4-(-1)=4+1=5

slope is 2/5

hope this helps

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
