Find the slope and the y-intercept of the of the linear equation.<br><br> 0=2-3y+12x
andrew11 [14]

The slope is 4 and the y-intercept is \frac{2}{3}

Step-by-step explanation:

The general form of a linear equation is Ax + By + C = 0, where

  • A is the coefficient of x
  • B is the coefficient of y
  • C is the numerical term
  • A, B, and C are integers
  • The slope of the line = \frac{-A}{B}
  • The y-intercept = \frac{-C}{B}

∵ The linear equation is 0 = 2 - 3y + 12x

- Switch the two sides and arrange the terms as the general

   form above

∴ 12x - 3y + 3 = 0

∴ A = 12

∴ B = -3

∴ C = 2

∵ The slope of the line = \frac{-A}{B}

- Substitute A by 12 and B by -3

∴ The slope of the line = \frac{-12}{-3}

∴ The slope of the line = 4

∵ The y-intercept = \frac{-C}{B}

- Substitute C by 2 and B by -3

∴ The y-intercept = \frac{-2}{-3}

∴ The y-intercept = \frac{2}{3}

The slope is 4 and the y-intercept is \frac{2}{3}
