Question

A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.

Answer 1

Explanation:

y - 2 = 1/2(x - 10)

y - 2 = 1/2x - 5

y = 1/2x - 3

Answer 2

Explanation:

You can read the slope right away.

y = 0.5x + b 1/2 = 0.5

The point will determine the y intercept

2 = 0.5*10 + b

2 = 5 + b

2-5 = b

b = - 3

The line is y = 0.5x - 3
