Write in equation of the line containing the points (-8,-8) and (-9,-10
myrzilka [38]

Answer:

y = 2x + 8

Step-by-step explanation:

Find the slope of a line between (-8,-8) and (-9,-10) using m = \frac{y_2-y_1}{x_2-x_1}, which is the change in y over the change in x.

Substitute in the values of x and y into the equation to find slope.

m= \frac{-10-(-8)}{-9(-8)}

Simplify.

Simplify the numerator.

Multiply -1 by -8

m=\frac{-10+8}{-9-(-8)}

Add -10 and 8

m=\frac{-2}{-9-(-8)}

Simplify the denominator.

Multiply -1 by -8

m=\frac{-2}{-9+8}

Add -9 and 8.

m=\frac{-2}{-1}

Divide -2 by -1.

m=2

Using the point slope form y-y_1=m(x-x_1) plug in m = 2, x_1 = -8, y_1 = -8

y-(-8)=(2)(x-(-8))

Solve for y.

Multiply -1 by -8

y + 8 = ( 2 ) ( x − ( − 8 ) )

Simplify  ( 2 ) ( x − ( − 8 ) ) .

Multiply  − 1  by  − 8

y+8 = 2 ( x + 8 )

Apply the distributive property.

y + 8 = 2 x + 2 ⋅ 8

Multiply  2  by  8 .

y + 8 = 2x + 16

Move all terms not containing  y  to the right side of the equation.

Subtract  8  from both sides of the equation.

y = 2 x + 16 − 8

Subtract  8  from  16 .

y = 2 x + 8

How do you solve 9 tenths minus 13 fiftenths
Elena L [17]

Answer:

0.04

Step-by-step explanation:

1. 9/10 = 0.9 and 13/15 = 0.86

2. Subtract 0.9 and 0.86

3. You should end up with 0.04

Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.

a snowball is rolled down a giant hill. the radius of the snowball grows. every second the radius increases by 0.36 inches. four
Bad White [126]

Based on the fact that the radius of the snowball increases by 0.36 inches every second, the linear function can be found to be y = 0.36x + 1.66

<h3>How to find the linear function?</h3>

The linear function is the function that shows how to change in the rate of the independent variable would affect the rate of change in the dependent variable.

The linear function takes the form:

y = mx + b

y = dependent variable

m = slope or change in radius of snowball

x = seconds

b = y-intercept

Solving for the y-intercept gives:

3.1 = 0.36(4) + b

b = 3.1 - 1.44

= 1.66

The linear function is therefore:

y = 0.36x + 1.66
