Answer:

3

Step-by-step explanation:

slop formula:

y2-y1

____

x2-x1

y2 is 9 and y1 is 3, so y2-y1 is 6

x2 is 3, x1 is 1, so x2-x1 is 2

6/2=3

Answer:

The two lines are neither

Step-by-step explanation:

∵ The equations of the lines are

∵ In the 1st equation a = 8 and b = 1

∴ m1 = [tex]\frac{-8}{1}[/tex] = -8

∴ The slope of the 1st line is -8

∵ In the 2nd equation a = 4 and b = 3

∴ m2 = [tex]\frac{-4}{3}[/tex]

∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]

→ By using the facts above

∵ m1 ≠ m2

∴ The two lines are not parallel

∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]

∴ m1 × m2 ≠ -1

∴ The two lines are not perpendicular

∴ The two lines are neither parallel nor perpendicular

Hope you can understand what i mean

Answer:

Step-by-step explanation:

First you need to find the Slope Intercept form or find the point and slope.

The point is: (-2,3)

and the slope is: 1/2

y - 3 = 1/2(x + 2)

y - 3 = 1/2x + 1

y = 1/2x + 1 + 3

y = 1/2x + 4

Slope intercept form: y = 1/2x + 4

Step-by-step explanation:

Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.

A fraction represents a part of a whole.

We need to calculate his typing speed for each attempt.

On his first attempt, Eli typed 180 words in [tex]1\frac{1}{2}[/tex] hours, which is the same as typing 120 words in 1 hour.

Therefore, his typing speed on the first attempt was 120 words per minute.

On his second attempt, Eli typed 180 words in [tex]1\frac{1}{5}[/tex] hour, which is the same as typing 150 words in 1 hour.

Therefore, his typing speed on the second attempt was 150 words per minute.

Comparing the two speeds, we see that Eli was faster on his second attempt, typing 150 words per minute compared to 120 words per minute on his first attempt.

Therefore, Eli typed faster on his second attempt, 120 words per minute on his first attempt and 150 words per minute on his second attempt.

Answer:

Side known in ratio as 8: 32

Side known in ratio as 9: 36

Side known in ration as 10: 40

Step-by-step explanation:

We can add all the numbers in the ration to form the sum of all the sides, or also equal to perimeter. 8+9+10 equals 27.

So we can write 27x=108

x=4. Multiply 4 to 8, then 9, then 10. You get 32, 36, 40

Answer: 41/365

Step-by-step explanation:

The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).

The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.

Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.

Answer:

  10x -30y = 3

Step-by-step explanation:

In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point

  2x -6y = 2(-3.9) -6(-1.4)

  2x -6y = 0.6

Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.

  10x -30y = 3

Answer:

1) slope = 1/5

x - intercept = (10, 0)

y - intercept = (0,-2)

2) use the method I used for number one to do number 2.

Step-by-step explanation:

slope = rise/run = y2-y1/x2-x1

1)

use any 2 points on a line. Chose one y-value which is y2 and the corresponding x-coordinate is x2. In the other coordinates, the y-value is y1 and the x-value is x1. Let's use points:

(-10, -4)

(-5, -3)

y2 = -3, which means:

y1 = -4

x1 = -10

x2 = -5

plug in the values:

-3-(-4)/-5-(-10)

=1/5

X - intercept is when y = 0. Plug in 0 for y when you see it.

x-0 = 10

x=10

x-intercept = (10,0)

Same for y intercept, except x = 0 this time.

0-5y=10

-5y=10

y=-2

y-intercept = (0,-2)
