The point-slope form of the equation of the line that passes through (-4, -3) and (12, 1) is y– 1 =1/4 (x – 12). What is the sta
Lorico [155]

Answer:

x-4y = 8

Step-by-step explanation:

y– 1 =1/4 (x – 12)

Multiply each side by 4

4y -4 = x-12

Subtract x from each side

-x +4y -4 = -12

Add 4 to each side

-x+4y -4+4 = -12 +4

-x+4y = -8

Multiply by -1

x-4y = 8

6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.

General formula for triangle area
a = 1/2 × b × h

plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45

The area of the triangle is 45 units²

A system of equations is shown below:
ivolga24 [154]
To solve this problem you must apply the procceddure shown below:

 1. You have the following system of equations:
<span>
 x+y = 3 
 2x–y = 6

 2. Then, you must clear the variable y from the first equation and susbtitute it into the second equation, as below:

 x+y=3
 y=3-x

 2x-y=6
 2x-(3-x)=6
 2x-3+x=6
 3x=6+3
 3x=9

 3. Therefore, the value of x is:

 x=9/3
 x=3

 4. As you can see, the correct answer is:

 x=9
