The answer should be y=x-2. To solve other questions like these, find the y-intercept on the y-axis and use rise over run to count the slope between the points. Here it rises 3 and runs 3, simplifying to one. The y-axis crosses at -2. Plug this into y=mx+b and you get y=x-2

Answer:

3 1/3

Step-by-step explanation:

Multiply both sides by the reciprocal of the coefficient of c.

(5/2c)(2/5) = (8 1/3)(2/5)

c = (25/3)(2/5) = 50/(3·5) = 10/3

c = 10/3 = 3 1/3

mote1985 [20]

Answer:

The coordinates of the fourth vertex is ( 2.1 , -3.6)

Step-by-step explanation:

Given:

The vertices are ( -2.3 and −3.6), (−2.3, and 2.2), and (2.1, and 2.2).

To Find :

The fourth coordinate = ?

Solution:

Let (a,b) be the missing coordinates

Now let us use the the mid point formula and find the missing coordinate.

Let ( -2.3 ,−3.6) be the point A

Let (−2.3,2.2) be the point B

Let (2.1, 2.2) be the point C

The mid point of AC should be BD

Step 1: Finding The mid pint of AC

The mid pint of AC

$(\frac{(-2.3+2.1)}{2} , \frac{(-3.6+2.2)}{2})$

$(\frac{(-0.2)}{2} , \frac{(-1.4)}{2})$

$(-0.1, -0.7)$

Step 2: Lets Equate the midpoints'

The mid pint of BD

=> $(\frac{(a+(-2.3))}{2} , \frac{(b+2.2)}{2})$ = (-0.1, -0.7)

$\frac{(a+(-2.3))}{2} = -0.1$

$(a-2.3) = -0.1 \times 2$

$(a-2.3) = -0.2$

$a = -0.2 +2.3$

a = 2.1

$\frac{(b+2.2)}{2} = -0.7$

$(b+2.2)= -0.7 \times 2$

$(b+2.2)= -1.4$

$b= -1.4 -2.2$

b = -3.6

What is the solution to the equations x^2-2x+y=8 and x-y=-2

kherson [118]

Hello!!

For the first equation:

$-2x + x^2 + y = 8$ (Solve for y)

$y = -x^2 + 2x +8$

For the second equation:

x - y = -2 (Solve for y)

-y = -x - 2

-y = x + 2

Good luck :)
