Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , thus

y = 3x + c ← is the partial equation

To find c substitute (1, - 2) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of line

Need an answer for both plez.
Ilya [14]

Answer:

(2, 13)

Step-by-step explanation:

Since they both equal y, you can equal them to each other.

8x - 3 = 2x + 9

Subtract 2x from both sides.

6x - 3 = 9

Add 3 to both sides.

6x = 12

Now divide 6 on both sides.

x = 2

Now that we have found x, we need to find y. Just plug in x to the equations.

y = 2(2) + 9

y = 4 + 9

y = 13

Now, if the next equal has the same y, then both are true.

8(2) -3 = y

16-3=y

13 = y

So therefor, both x and y are true.

|x-8|&lt;13<br> What is the solution
maks197457 [2]

Answer:

  • x = (-5, 21)

Step-by-step explanation:

  • |x - 8| < 13

1 .

  • x - 8 < 13
  • x < 8 + 13
  • x < 21

2.

  • x - 8 > -13
  • x > 8 - 13
  • x > -5

<u>Combined answer</u>

  • -5 < x < 21
  • x = (-5, 21)
