Answer 1

The equation of the lines in the graphs given are:

Graph 1: y = -2x - 4

Graph 2: y = -x + 2

Graph 3: y = 4x - 4

Graph 4: y = x + 2

What is the Equation of the Line?

The equation of a line is given by the general formula:

y = mx + b

Where:

m = slope

b = y-intercept.

Equation of the Line in Graph 1:

Slope = rise/run = -4/2 = -2

b = -4

Equation is: y = -2x - 4

Equation of the Line in Graph 2:

Slope = rise/run = -2/2 = -1

b = 2

Equation is: y = -x + 2

Equation of the Line in Graph 3:

Slope = rise/run = 4/1 = 4

b = -4

Equation is: y = 4x - 4

Equation of the Line in Graph 4:

Slope = rise/run = 2/2 = 1

b = 2

Equation is: y = x + 2
