Question

What is the equation of the line that passes through the point (-1, 4) and has a
slope of —5?

Answer 1

Hey there,

So in order for us to write the equation we need to know the y-intercept.

We use the slope intercept form to solve for that:

y = mx + b

We plug in the slope and the point:

• 4 = -5(-1) + b

Now we solve for b:

• -1 = b

Since we have the y-intercept and the slope now we can write it in the equation:

• y = -5x - 1

Hope I helped,
