Question

Question, How do you find the equation of a line when given the x and y intercept?

Answer 1

Use the two points to find the slope. You are given the y intercept. Now you know the slope and the y intercept. Use slope-intercept form and write the equation.

Answer 2

I just plug in the slope for M?

Answer 3

yes

Answer 4

So if I have x intercept -5 and y intecept -2 the equation would look like this?

y = -2/5x - 2

Answer 5

Those familiar with the "Intercept Form" will solve this a LOT faster.

"x intercept -5 and y intecept -2"

\(\dfrac{x}{-5} + \dfrac{y}{-2} = 1\) -- Done!

If you need some other form after that, well, algebra away!
