Equation of line passes through (5,-1) and (4,-5)

y+1 = 4(x-5) or y+5 = 4(x-4) or y=4x-21

Step-by-step explanation:

slope m =

using points given, slope m = (-1+5)/(5-4) = 4/1=4

point slope formula: y-y1 = m(x-x1)

use any point for y1 and x1

y+1 = 4(x-5) or y+5 = 4(x-4)

y=4x-20-1 = 4x-21

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
