Answer: see below

Explanation:

Step 1: Find the slope (m) using the formula:
m=(y_2-y_1)/(x_2-x_1)

Step 2: Plug in the slope (m) and one of the points (x₁, y₁) into the Point-Slope formula. y - y₁ = m(x - x₁)

1. (0, -2) and (3, 0)

Step 1:
m=(-2-0)/(0-3)\quad =(-2)/(-3)\quad =(2)/(3)

Step 2:
y-0=(2)/(3)(x-3)


y=(2)/(3)(x-3)


\large\boxed{y=(2)/(3)x-2}

2. (0, -3) and (-4, -5)

Step 1:
m=(-3-(-5))/(0-(-4))\quad =(-3+5)/(0+4)\quad =(2)/(4)\quad =(1)/(2)

Step 2:
y-(-3)=(1)/(2)(x-0)


y+3=(1)/(2)x


\large\boxed{y=(1)/(2)x-3}

3. (0, -3) and (-4, -5)

Step 1:
m=(-4-3)/(-3-4)\quad =(-7)/(-7)\quad =1

Step 2:
y-3=1}(x-4)


y-3=x-4


\large\boxed{y=x-1}
