Write an equation for (-1,-2),(-3,-4)

Mathematics
1 answer:
Marina86 [1]3 years ago

Answer:

y=x+1

Step-by-step explanation:

First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:

-4--2/ -3--1= -2/-2= 1

so the slope is 1

Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b

-3=-4+b

1=b

now plug the slope and y intercept in:

y=x+1

hope this helps :D

valentinak56 [21]

Answer:

The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88

Step-by-step explanation:

The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:

Between

83 - 6.5 = 76.5

83 + 6.5 = 89.5

So:

The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88

Answer:

B

Step-by-step explanation:

since y and x vary directly the equation relating them is

y = kx ← k is the constant of variation

to find k use any ordered pair from the list given

using x = 4 when y = - 2, then

k = \frac{y}{x} = \frac{-2}{4} = - 0.5 → B

I just want to make sure: A baseball is traveling (+20 m/s) and is hit by a bat. It leaves the bat traveling (-30 m/s). What is
g100num [7]

Answer:

50m/s

Step-by-step explanation:

We assum the direction the baseball is travelling to the bat is the positive direction at 20 m/s and is hit in the opposite at a faster speed. The change in velocity is the final velocity minus the initial velocity:

=20-(-30)=50

The change in velocity is 50m/s
