Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use:
Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is 1/2
Step 4: Substitute those values into the point-slope form.
y - y1 = m(x - x1)
y - 3 = (x - 1)
Which of Talia's steps is incorrect?
