Answer and Step-by-step explanation: Equations of line through points and slope can be determined by:

$y-y_{0}=m(x-x_{0})$

m is slope

Point (2,-4) and y-intercept = -2

Y-intercept is point (0,-2)

m = $\frac{y_{a}-y_{b}}{x_{a}-x_{b}}$

m = $\frac{-4-(-2)}{2-0}$

m = - 1

Equation:

y+2=-1(x-0)

y=-x-2

Points (4,2) and (3,1)

m = $\frac{2-1}{4-3}$

m = 1

Equation:

y-2=(x-4)

y=x-2

Point (3,2) and slope = -2

m = -2

Equation:

y-2=-2(x-3)

y=-2x+6+2

y=-2x+8
