Question

The sum of slope and y-intercept of the line 2x + 3y = 1 is

  1. 1 half
  2. 2 over 3
  3. fraction numerator negative 1 over denominator 3 end fraction
  4. fraction numerator negative 2 over denominator 3 end fraction

hintHint:

The y-intercept is the point on the y-axis where the line crosses. When x = 0, it is called y-axis. To find the y-intercept, substitute x with 0.

The correct answer is: fraction numerator negative 1 over denominator 3 end fraction


    2 x space plus space 3 y space equals space 1
2 open parentheses 0 close parentheses space plus space 3 y space equals space 1
0 space plus space 3 y space equals space 1
3 y space equals space 1
y space equals space 1 third
