Question

The points (0, 1) and (-9, -9) fall on a particular line. What is its equation in slope-intercept form?

Answer 1

The slope-intercept form:

`y=mx+b\\\\m=(y_2-y_1)/(x_2-x_1)`

m - slope

b - y-intercept → (0, b)

We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.

Calculate the slope:

`m=(1-(-9))/(0-(-9))=(10)/(9)`

Answer:
`y=(10)/(9)x+1`
