Can someone help me what is the answer
Varvara68 [4.7K]

Answer:

y = 4x + 3

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 )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (0, 3)

m = \frac{3+1}{0+1} = \frac{4}{1} = 4

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = 4x + 3 ← equation of line

Honors algebra!! Plz help #22
ollegr [7]

Answer:

8

Step-by-step explanation:

12 times x (the first square) is equal to 16 times x-2 (the second square)

12x = 16(x-2)

Distributed

12x = 16x-32

Simplified (divided by 16)

0.75x = x-2

Subtract x from both side of the equation

-0.25x = -2

Both negatives cancel each other out

0.25x = 2

0.25 times what equals 2,...

x = 8

Hope it help,... and I'll see you in life,... well not really, but you get the idea,... Chow,...!

MaryJo decided to solve the equation 3x-2= -x-6 by entering each of the expressions into her graphing calculator. To solve the e
miss Akunina [59]
Note that the problem states that you only need to check the solution she got for x...so we don't have to worry about y in this case. (YAY)

To verify MaryJo's answer, simply solve the equation for x:

3x - 2 = -x - 6
3x (+ x) - 2 = -x (+ x) - 6
4x - 2 = -6
4x - 2 (+ 2) = -6 (+ 2)
4x = -4
4x/4 = -4/4
x = -1

Since this conforms to MaryJo's answer, she did indeed find the correct solution for x.
