Note:

Your first question is missing the y-intercept, so I am solving the 2nd question, but the procedure to solve each of the questions is the same.

Answer:

The equation in the standard form is:


(2)/(3)x\:+\:y\:=-4

Explanation:

Given

Slope m = -2/3

y-intercept = -4

We know that the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

now substituting m = -2/3 and y-intercept b = -4 in the slope-intercept of the line equation


y = mx+b


y\:=\:-(2)/(3)x\:\:+\:\left(-4\right)


y\:=\:-(2)/(3)x\:-4

We know that the equation in the standard form is


Ax + By = C

where x and y are variables and A, B and C are constants

so writing the equation in the standard form


y\:=\:-(2)/(3)x\:-4


(2)/(3)x\:+\:y\:=-4

Therefore, the equation in the standard form is:


(2)/(3)x\:+\:y\:=-4
