Question

A line has a slope of -7 and passes through the point (0, -7). Is it possible to write the equation

of the line without doing any work? Explain why or why not?


Thank you!

Answer 1

Answer: yes

Step-by-step explanation: they have to be past 0 to start

Answer 2

y = -7x -7

Step-by-step explanation:

y - y₁ = m ( x - x₁ )

y - -7 = -7 ( x - 0 )

y + 7 = -7x

y = -7x -7

Or using the formula:

y = mx + b

y = -7x - 7

using this formula, if only passes y-axis, we can find equation without doing any work.
