Question

write y-3=-1 (x+7) in standard form

Answer 1

Multiply −1 by each term inside the parentheses.
y−3=−x−7

Since −3 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 3 to both sides.
y=3−x−7

Simplify the right-hand side of the equation.
y=−x−4
