Answer:

y=-2/7x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-5-(-1))/(21-7)

m=(-5+1)/14

m=-4/14

simplify

m=-2/7

y-y1=m(x-x1)

y-(-1)=-2/7(x-7)

y+1=-2/7(x-7)

y=-2/7x+2-1

y=-2/7x+1

Fill in the given values and simplify.

$\dfrac{g(x+h)-g(x)}{h}=\dfrac{\dfrac{1}{x+h}-\dfrac{1}{x}}{h}\\\\=\dfrac{x-(x+h)}{h\cdot x(x+h)}\\\\=\dfrac{-1}{x(x+h)}$

kirill115 [55]

Given :

2 - 1/2y = 0

To find :-

The gradient form .

Solution :-

The gradient form/ slope intercept form

y = mx + c ,

On converting ,

2 - 1/2y = 0
1/2y = 2
y = 2*2
y = 4
y = 0x + 4

Using elimination method, what will be the value of y after solving -x - y = 5 and -x + 4y = 15?

Answer:

y = 2

Step-by-step explanation:

The variable x can be eliminated by subtracting the first equation from the second.

(-x +4y) -(-x -y) = (15) -(5)

5y = 10 . . . . . . . simplify

y = 2 . . . . . . . . . divide by 5
