In the given figure, let's find the slope (m) of the line :


  • (y2 - y1)/(x2 - x1)


  • (0 - ( - 2))/( - 3 - 0)


  • - (2)/(3)

y - intercept (c) = -2

Equation of line will be :


  • f(x)= mx + c


  • f(x) = - (2)/(3) x - 2

hence, correct choice is B

Answer:

  • B. f(x) = -2/3x - 2

Explanation:

Use points:

  • (-3, 0) and (0, -2)

Find the slope:

  • m = -2/(0 - (-3)) = -2/3

The y- intercept is -2.

The line is:

  • f(x) = -2/3x - 2

Correct choice is B
