HELP HELP HELP<br><br> Just 5 quick algebra 1 questions for 100 points!

1. x = a

2. y = b

3. The slope of a vertical line is undefined..

4. Change in y/change in x (m) or rise/run

5. Rewrite the equation in slope-intercept form to find the value of the y-intercept. The value of x will always be 0.

<h3>What is the Equation of a Line?</h3>

The equation, y = mx + b, in slope-intercept form, defines a line, where m is the slope and the y-intercept = b.

1. Slopes of vertical lines are always undefined, therefore, for a vertical line that contains (a, b), the equation would be: x = a.

2. Horizontal lines have a slope of 0, therefore, the equation of a horizontal line that contains the point, (a, b), will  be: y = b.

3. The slope of a vertical line is undefined.

4. Two ways of finding the slope if we are given two points on a line are:

Change in y/change in x (m) = y2 - y1 / x2 - x1

or

rise/run

5. If we have an equation in point-slope form, for example, y - 2 = 2(x - 4), rewrite the equation in slope-intercept form and find the value of the y-intercept:

y - 2 = 2x - 8

y = 2x - 8 + 2

y = 2x - 6

The y-intercept = -6, therefore, the coordinates of the y-intercept would be: (0, -6).

Pls help me...how do u factor that ?
Leya [2.2K]

Answer:

(2x - 1)(2x + 1)(x - 7)

Step-by-step explanation:

We use grouping to factor.

Step 1: Group 1st 2 terms together and factor

4x³ - 28x²

4x²(x - 7)

Step 2: Group last 2 terms together and factor

-x + 7

-1(x - 7)

Step 3: Combine

(4x² - 1)(x - 7)

Step 4: Factor out quadratic

(2x - 1)(2x + 1)(x - 7)

Which vectors represent the reflection of the vector &lt;3, -7&gt; across the x-axis? A. [3/7} B. [-3/7] C. &lt;-3, 7&gt; D. &lt
Alexandra [31]

Answer:

D)    < 3, 7)>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given that the vector < 3 , -7 >

Given the vector reflection across the x-axis

                   (x,y) → (x , -y)

The vector < 3,-7> →< 3, -(-7)>

                  < 3,-7> →< 3, 7)>
