$m=6 , \ \ \ (1, 1) \\ \\To \ find \ our \ equation \ we \ will \ use \ the \ formula: \\ \\ y - y _{1} = m(x - x _{1}), wherem \ is \ the \ slope \ and \ (x _{1}, y _{1}) \ is \ the \ point \\ \\m=6 , \ \ x_{1}=1 , \ \ y_{1} = 1\\\\y - 1 = 6(x-1)\\\\y-1=6x -6 \\\\y=6x-6+1\\\\y=6x-5$

Y=ax+b
slope is 6 so y=6x+b
point is putting to y=6x+b
1=6*1+b
b=-5
y=6x-5

10. 2x + 7y = 1<br> 2x - 4y = 12<br> Solve for y

adoni [48]

Answer:

The solution for y = -1.

Step-by-step explanation:

Given:

$2x\ +\ 7y\ =\ 1$ ....(1)

$2x\ -\ 4y\ =\ 12$ ....(2)

So, to solve for y, first we solve for x in equation (2):

$2x-4y=12$

⇒ $2x=12+4y$

Dividing both sides by 2,

⇒ $x=6+2y$

Now, substituting the value of x in equation (1):

$2x+7y=1$

⇒ $2(6+2y)+7y=1$

⇒ $12+4y+7y=1$

⇒ $12+11y=1$

⇒ $11y=1-12$

⇒ $11y=-11$

Dividing both sides by 11,

⇒ $y=-1$

Therefore, the solution for y = -1.
