Question

A line passes through the points (4, 0) and (–4, –8). What is its equation in slope-intercept form?

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

Answer 1

y = x - 4

Explanation:

1. Find the slope using the formula slope =
`\frac{y_(1) -y_(2) }{x_{1-x_(2) } }`

2. Use slope-intercept form y = mx + b

3. m = slope, x = the x coordinate in the set and b = where it crosses the y axis.

4. Answer is y = x - 4
