Question

The points (1,7) and (0,5) fall on a particular line. What is its equation in slope-intercept

form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
y = x +

Answer 1

y = 2x + 5

Explanation:

First find the slope:

5-7/0-1 --> -2/-1 --> (2)

Now use the point-slope form to find the slope-intercept form:

y-7 = 2 ( x - 1)

y - 7 = 2x - 2 add seven to both sides...

y = 2x + 5
