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 .
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?
step 1 is incorrect because it uses a point that is not on the line.
step 2 is incorrect because it uses a point that is not on the line.
step 3 is incorrect because it shows an incorrect ratio for the slope.
step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
