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.

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-y_{1}=m(x-x_{1})

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

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Instead of counting how many rights and how many ups.

What is the product of the polynomials below? (4x^2-2x-4)(2x+4)
Travka [436]

Answer:  8x³ + 12x² - 16x - 16

<u>Step-by-step explanation:</u>

  (4x² - 2x - 4)(2x + 4)

= (2x + 4)(4x² - 2x - 4)

= 2x(4x² - 2x - 4)  +  4(4x² - 2x - 4)

=   8x³ - 4x² - 8x   +  16x² - 8x - 16

=   8x³ + (-4x² + 16x²) + (-8x - 8x) - 16

=   8x³ + 12x² - 16x - 16

What is the slope of D and E??
Mazyrski [523]

Answer:

-4 and 0

Step-by-step explanation:

Rise over Run would give us the slope.

In the first graph, It goes down 4 while it goes 1 to the right.

This means that -4/1 = -4.

The second graph does not go up or down, meaning 0, while it goes 1 to the right.

This means that 0/1 = 0.
