Question

What is the equation of the line in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

y =
`(1)/(5)` x - 5

Explanation:

y = mx +b You have to find the slope and the y intercept

slope:

I used the two points on the graph (0,-5) and (5,-4) The slope is the change in y over the change in x. An ordered pair is given in the form (x,y)

`(- 4 - - 5)/(5-0)` =
`\frac{-4 + 5}5}` =
`(1)/(5)`

or you could just look at the two points. If you start at (0,-5) and go straight up one and the then go right 5 spaces, you will be at the point (5,-4)
`(1)/(5)`

The y intercept for the b is where the line crosses the x axis. It crosses at the point (0,-5) The -5 is the b part.
