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

Answers

Answer 1

Answer: From the steps Talia chooses to find the equation of the line, we shall evaluate the incorrect step as follows:
Step 1:
Choose a point in 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.
(5-3)/(2-1)=2/2=1
step 4:
Substitute those values into the point-slope form
y-y1=m(x-x1)
y-3=2(x-1)
y=2x+1
Thus the answer is:
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

Answer 2

Answer:

just took the test the right answer is step 3 is incorrect

-- PQS is a right triangle, because a tangent to a circle is
perpendicular to the radius at the point of tangency.

-- You know PQ (a leg) and PS (the hypotenuse) so you can
find the length of the other leg.

QS = (PQ)² - (PS)² = (4.2)² - (8.2)² = 7.043.

-- If you draw the radius PR, then you have another right triangle
back to back with the first one. Each hypotenuse is a radius, so
those are equal, and PQ is common to both triangles.
So RQ is equal to QS.

-- The length of the whole chord RS is double the length of QS .

RS = 2 x (QS) = 2 x (7.043) = 14.085 .

That looks a lot like the third choice down.

By the Pythagorean Theorem, QS is 7.04. It is well-known that QS=RQ in these circles, so QS+RQ=RS=14.08, which is closest to 14.1.
