Function

y = -3x - 13

• to find x-intercept/zero, substitute y = 0.

0 = -3x - 13

• move the variable to the left-hand side and change its sign.

3x = -13

• divide both sides of the equation by 3.

x = -13/3

answer:

x = -13/3

alternate form:

x = -4 ⅓ or x = -4.3

Rewrite in standard form

y = -3x - 13

• move the variable to the left-hand side and change its sign.

y + 3x = -13

• use the commutative properly to reorder the terms.

3x + y = -13

answer:

3x + y = -13
