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 comma 5 Open image in full-screen view Step 2: Choose another point on the line, such as 1 comma 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 half Step 4: Substitute those values into the point-slope form. y minus y sub 1 is equal to m times x minus x sub 1 y minus 3 is equal to 1 half times x minus 1 Which of Talia’s steps is incorrect?
Answer
A
Step 4 is incorrect because it shows an incorrect substitution of 1 comma 3 into the point-slope form.
B
Step 1 is incorrect because it uses a point that is not on the line.
C
Step 2 is incorrect because it uses a point that is not on the line.
D
Step 3 is incorrect because it shows an incorrect ratio for the slope.
