Write an equation for the line that passes through (1, -1) and (0, -4)

Y = 3x - 4

Step-by-step explanation:

find slope

(y2 - y1) / (x2 - x1)

(-4 + 1) / (0 - 1) = 3

plug one coordinate point into: y = mx + b

-1 = 3(1) + b

solve for b

b = -4

plug in numbers for m and b:

Y = 3x - 4

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
