Graph the linear equation with 3 points

Mathematics
1 answer:
barxatty [35]3 years ago
3 0

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

x-y=1

To graph the line find the intercepts

step 1

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

substitute in the linear equation

0-y=1\\y=-1

The y-intercept is the point (0,-1)

step 2

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

substitute in the linear equation

x-0=1\\x=1

The x-intercept is the point (1,0)

step 3

Find a third point

<em>Note</em>: It is important to specify that two points are sufficient to draw a line

assume the value of x=5

substitute in the linear equation and solve by y

5-y=1\\y=5-1\\y=4

so

The third point is (5,4)

step 4

Plot the points and connect them to graph the line

see the attached figure

The sum of the dibits of a two digit number is 15. The number obtained by interchanging its digits exceeds the given number by 9
QveST [7]

Answer:

  78

Step-by-step explanation:

Interchanging the digits of a 2-digit number changes the value by a multiple of 9. The multiple is the difference between the digits of the number.

So, we have two digits that add to 15, and have a difference of 9/9 = 1. Since you're familiar with your addition facts, you know that the two digits are 7 and 8. Since the number we're looking for is the smallest of the numbers you can make with those digits, ...

  the original number is 78.

_____

More formally, let t and o represent the tens and ones digits of the original number.

  t + o = 15 . . . . . . the sum of digits is 15

  (10o +t) - (10t +o) = 9 . . . . swapping digits increases the value by 9

The latter equation simplifies to ...

  9o -9t = 9 . . . . collect terms

  o - t = 1 . . . . . . divide by 9 . . . (note the difference of digits is 9/9=1)

Adding this to the first equation gives ...

  (t +o) +(o -t) = (15) +(1)

  2o = 16

  o = 8

  t = o -1 = 7

The tens digit is 7 and the ones digit is 8: 78.

PUT THESE NUMBERS IN ORDER GREATEST TO LEAST ✔✔ I WILL ADD BRAINLIST
Fiesta28 [93]

Answer:

2 12/16, 2 18/25, and lastly 2.

Step-by-step explanation:

Since 2 is least, we can put that at the end. That leaves us with 2 18/25 and 2 12/16. Since 12/16 is greater, we will put that as the greatest. 2 18/25 is in the middle. Hope this helps!

Y=3x-2 what is the value of y? when y=-1/3
Olin [163]
Oddly enough, when y=-1/3, the value of y is -1/3.

When x = -1/3, the value of y is
.. y = 3*(-1/3) -2
.. = -1 -2
.. = -3

When x = -1/3, the value of y is -3.
