How do you find the slope of a line? How do you know if two lines are parallel? give examples

Answers

Answer:

finding slope: The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

parallel: We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

hope this helps!

Answer:

The slope of a line is the rise/run of how far away the points are from each other. Say you have the equation y=3/4x-6, the slope is 3/4 so that means you plot your first point at -6 on the y-axis, because that is your y-intercept, and then you will go up 3, right 4. You will continue to do this until you have enough points to make a line. When two lines are parallel, they will always have the same slope. So the lines y=1/2x+4 and y=1/2x-3 are parallel because not only do they have the same slope, they do not intersect at all, which is a requirement for parallel lines. I hope this helps!!

the answer would be x = 1

Answer:

x = 1

Step-by-step explanation:

1/2(8x-6) = -1/3(9x-12)   distribute

4x-3 = -3x+4                 add 3x to both sides

7x-3 = 4                        add 3 to both sides

7x = 7                            divide by 7 on both sides

x = 1

78

Answers

Answer:

78

Step-by-step explanation:

Since the base angles are congruent, then the triangle is isosceles and

AB = BC , that is

5x - 19 = 2x + 11 ( subtract 2x from both sides )

3x - 19 = 11 ( add 19 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

Then

AB = BC = 2x + 11 = 2(10) + 11 = 20 + 11 = 31

Thus

perimeter = 31 + 31 + 16 = 78

Answer:

I think she mowed 6 lawns.

Step-by-step explanation:

Answer:

1 lawn each week

Step-by-step explanation:

Rocco lawns mowed each week=x

Carly's lawns mowed each week=x+2

Equation to show how much Carly lawned for 6 weeks

18 is the total amount of lawns

6 is the number of weeks

6(x+2)=18

Solve for x

6x+12=18

Subtract 12 on both sides

6x=6

x=1

x is the amount that Rocco lawned

The distance between 2 cities is 7,200 miles. How long will it take a plane that flies at 600 miles h to travel between the 2 cities?​

Answers

Answer:

It would be 12 hours for the plane to go from a city to another/the other city

Step-by-step explanation:

(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)

If you would apply the formula for time then

7,200m ÷ 600m/h = 12 hours

The plane flying at 600 miles per hour can cover a distance of 7200 miles in 12 hours.
