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.

Step-by-step explanation:

Answer with explanation:

To determine the Equation of line in Point slope form

1.Choose a point on the line, such as (2, 5)

2. Choose another point on the line, such as (1, 3).

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 2.

4.Substitute those values into the point-slope form.

y-3=2(x-1)

Step 3 is incorrect because it shows an incorrect ratio for the slope.

To determine the slope we use the following formula

Instead of counting how many rights and how many ups.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

hi there, i would be interested to you with your test, may you add the questions and answer options.
