What is y+8=-5(x+3) in standard form
Papessa [141]

Answer:

-5x + y = -27

Step-by-step explanation:

Equation: y+8 = -5(x+3)

Standard form is (ax + by = c)

We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.

y + 8 = -5 (x + 3)

y + 8 = -5x -15

y = -5x - 27

THE ANSWER IS :

-5x + y = -27
