Answer:

y intercept is 3.5 or 3 1/2

Step-by-step explanation:

y=mx+b

substitute the ordered pair (-1,4) in place for y and x in the equation; substitute the slope of -1/4 in place of m to solve for "b"

4= -1/4(-1) +b

4= 2/4+b

subtract 2/4 from both sides

b= 3 2/4 which reduces to 3 1/2 or in decimal form 3.5
