<h2>Finding the slope of a line given the graph</h2><h3>Answer:</h3>

7) \frac{1}{2}\\

8) -\frac{5}{4}\\

<h3>Step-by-step explanation:</h3>

<em>Please refer to my Answer from this question to know more about the slope of a line: <u>brainly.com/question/24599351</u></em>

In graph 7, we can see that the points, (-1,-4) and (1, -3) are on the line so these can be our points 1 and 2. Now we can find the slope.

\frac{-3 -(-4)}{1-(-1)} \\ \frac{-3 +4}{1 +1} \\ \frac{1}{2}

The slope of line in graph 7 is \frac{1}{2}\\.

In graph 8, we can see that the points, (-4,4) and (0, -1) are on the line so these can be our points 1 and 2. Now we can find the slope.

\frac{-1 -4}{0-(-4)} \\ \frac{-1 -4}{0 +4} \\ \frac{-5}{4} \\ -\frac{5}{4}

The slope of line in graph 8 is -\frac{5}{4}\\.

Y = 4x - 5 and (3,4) (7, 3) A. parallel B. perpendicular D. neither
s344n2d4d5 [400]

Answer:

<em>The lines are perpendicular. </em><em>Option B.</em>

Explanation:

<u>Equation of the Line</u>

One of the characteristics of the line is its slope. It can be determined in two ways:

* From the equation y=mx+b, the m is the slope. The given equation is y=4x-5. Thus, the slope of this line is m=4.

* Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

The points are (3,4) and (7,3), thus the slope is:

\displaystyle m=\frac{3-4}{7-3}=-\frac{1}{4}

A. For two lines to be parallel, their slopes must be equal. Since m1=4 and m2=-1/4, the lines are not parallel. Incorrect

B. For two lines to be perpendicular, their slopes must meet the condition:

m1*m2=-1

4*(-1/4)=-1

Both lines are perpendicular. Correct choice

D. Since choice B. is correct, this cannot be true. Incorrect

Help please!!!!!!!!!
MAVERICK [17]

Answer:

Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees

Step-by-step explanation:

Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)

-0.8 mhm :)

how: u add them all up n then divide by how many numbers there are !! in this case: 2+2+-2+-4+-3+0 = -5 and there’s 6 numbers and then 5/6 is .83 repeated but u just round to .8 because, “four or less, give it a rest ... five or more raise the score!” that’s how i remember :) i already saw an answer for this but i decided to explain anyways in case u didn’t understand. have a great day<3
