Practice writing linear equations given two points.

The first step of writing an equation when given two points is the same for both strategies, slope-intercept or point-
slope forms. What would be the first step in finding the equation of the line that passes through (5, 1) and (3, 5)?
Assignment
O create a graph using the two points
O find the slope
O find the y-intercept
O substitute one point's coordinates into either form

Answer is to find the slope using slope formula (y2 - y1) over (x2 - x1)
Or change in y over change in x.

Step-by-step explanation

Once you find slope, you can write your equation using slope intercept or point slope formula. Both use slope in the formula.
