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 th 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. e slope. step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form.
