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

Dafna11 [192]

The incorrect step in Talia's solution is the step 4 which is "step 4 is incorrect because it shows and incorrect substitution of slope value into the point-slope form". The correct steps are as follow:
step 1: choose a point on the line which is (2,5)
step 2: choose another point on the line which is (1,3)
Step 3: determine the slope which is m = rise / run. The line runs 1 unit and rises 2 units so the slope is m = 2/1
step 4: substitute point on the line (2,5) and the slope of the line such as:
y-y1 = m (x-x1)
y-5 = 2 (x-2)

This is the correct steps.
