A line contains the points (4,5) and (3, -9). Write the equation of the line using point-slope form.

neonofarm [45]

Answer:

Step-by-step explanation:

original formula is: y - y1 = m (x - x1) ordinates= (x1, y1)

insert the a corresponding x and y coordinate:

y + 3 = -2 (x + 9)

Don't forget to change the signs depending on whether their positive or negative:

(3, -9) since 3 is positive but there is a minus in the formula it would be -3

since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)

Find the indicated area under the curve of the standard normal distribution; then convert it to a percentage and fill in the bl

galben [10]

Answer:

95%

Step-by-step explanation:

About 95% of the area is within two standard deviation in standard normal distribution. This can be explained by finding the probability within 2 standard deviation using standard normal distribution.

P(z1<Z<z2)=P(-2<Z<2)

P(-2<Z<2)=P(-2<Z<0)+P(0<Z<2)

P(-2<Z<2)=0.4772+0.4772

P(-2<Z<2)=0.9544

Thus, About 95% of the area is between z2 and z2

bonufazy [111]

Given that S<span>taci must vacuum 1/2 of the house.

If she already has vacuumed 1/3 of her share tonight the part of the house she has vacumed is given by

$\frac{1}{3} \ of \ \frac{1}{2} = \frac{1}{3} \times \frac{1}{2} = \frac{1}{6}$

Therefore, she has vacuumed 1/6 of the house.

Which equation represents the line that passes through the points (2,7) and (1,5)

Dimas [21]

Answer:

First we get the slope of line with points (2,3) & (1,5):

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

m=%285-3%29%2F%281-2%29=2%2F%28-1%29

m=-2, slope

Knowing the slop, we can get the intercept in point (1,1):

y=mx%2Bb, SLOPE- INTERCEPT

1=-2%281%29%2Bb

b=1%2B2=3

so, the eqn of the line: highlight%28y=-2x%2B3%29

The line with points (2,3) & (1,5): same slope because parallel, we'll check

VIA POINT SLOPE FORM:

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

m=%285-3%29%2F%281-2%29=2%2F-1 ----> m=-2, same right?

For the intercept thru pints (2,3):

Via SLOPE INTERCEPT FORM, we pick points (2,3)

3=-2%282%29%2Bb

b=3%2B4=7 ----> y intercept. The same value if you pick points (1,5).

Eqn of line: y=-2x%2B7 (Green line) parallel to y=-2x%2B3 (Red line)

See the graph,

--- see red line, it passes at point (1,1). Also green line passes points (2,3) & (1,5)
