Question

Which equation represents a line which is parallel to the line 7x+3y=−3?

Answer 1

Explanation:

3y = -7x - 3

y = -7/3x - 1

Answer 2

• y = -7/3x + b

Explanation:

Given function:

• 7x+3y=−3

Rewriting in slope-intercept form:

• 3y = - 7x - 3
• y = -7/3x - 1

Parallel lines have a same slope

So the line parallel to the given will have a formula:

• y = -7/3x + b
