Question

A line passes through the points (0, 3) and (10, 2). What is its equation in slope-intercept form?

Answer 1

Answer:

1. Find slope.

slope(m)

$= \frac{y2 - y1}{x2 - x1}$

$\frac{2 - 3}{10 - 0} = \frac{ - 1}{10}$

2. Substitute any point. (either (0,3) or (10,2) to find the y-intercept (b)

y=mx+b

3=-1/10+b

b=31/10 or 3.1

so the final answer is

y= - 1/10 + 31/10 or y= - 0.1 + 3.1
