Write the equation of the line passing through (−1, 0) and (0, −3).

y = -3x -3

Step-by-step explanation:

We have two points so we can find the slope

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

m = (-3-0)/(0--1)

   = (-3-0)/(0+1)

   = -3/1

  = -3

We have the slope and the y intercept (where x=0) The y intercept is -3

y = mx+b  where m is the slope and b is the y intercept

y = -3x -3

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
