Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form. (2,8), and (8,2)
leonid [27]

Answer:

y=-x+10

Step-by-step explanation:

Hi there!

Slope intercept form: y=mx+b where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Find the slope (m)</u>

m=\frac{y_2-y_1}{x_2-x_1} where the two given points are (x_1,y_1) and (x_2,y_2)

Plug in the given points (2,8),and (8,2)

​m=\frac{2-8}{8-2}\\m=\frac{-6}{6}\\m=-1

Therefore, the slope of the line is -1. Plug this into  y=mx+b:

y=-x+b

<u>2) Find the y-intercept (b)</u>

y=-x+b

Plug in a given point and solve for b

8=-2+b

Add 2 to both sides

8+2=-2+b+2\\10=b

Therefore, the y-intercept is 10. Plug this back into y=-x+b:

y=-x+10

I hope this helps!

You and your friend were taking turns rolling a die when you thought of a game: If a one is rolled by either player, you pay you
Mazyrski [523]

Answer:

6 times

Step-by-step explanation:

1. There was no cents left

2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)

3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)

4. It equals 6 and 6 is a even number

5. Sorry this was too confusing
