slope = (3 - 1)/(-2 + 4) = 2/2 = 1

equation
y - 1 = x + 4
y  = x + 5

answer
y  = x + 5

Answer:

Equation of line is y = x+5

Step-by-step explanation:

The line is passing through the points (-4,1) And (-2,3).

Slope of the line is given by

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{3-1}{-2+4}\\\\m=\frac{2}{2}\\\\m=1[/tex]

Point slope form of a line is given by

[tex]y-y_1=m(x-x_1)[/tex]

Substituting the known values

[tex]y-1=1(x-(-4))[/tex]

On simplifying, we get

[tex]y-1=x+4\\\\y=x+5[/tex]

Equation of line is y = x+5
