When (1,2) is substituted into the first equation, the equation is true.
The ordered pair (1,2) is a solution to the system of linear equations.
When (1,2) is substituted into the second equation, the equation is true.

To solve, plug the value of the variables in each equation in the system

(1,2) means x = 1 and y = 2

y = -2x + 4

2 = -2(1) + 4

2 = -2 + 4

2 = 2

the ordered pair is a solution to the first equation

7x - 2y = 3

7(1) - 2(2) = 3

7 - 4 = 3

3 = 3

the ordered pair is a solution for the second equation

Because the ordered pair is a solution for BOTH equations in the system, it is a solution to the system. Therefore, the correct answers are:

"When (1,2) is substituted into the first equation, the equation is true."

"The ordered pair (1,2) is a solution to the system of linear equations."

"When (1,2) is substituted into the second equation, the equation is true."

Hope this helps!

A circle is centered at the point (-7, -1) and passes through the point (8, 7).

Elan Coil [88]

Radius = √(7-(-1))² + (8-(-7))² = √8²+15² = √289 = 17

Let the point be (-15,y)
(-15-(-7))² + (y-(-1))² = 17²
⇒ -8² + (y+1)² = 17²
⇒ 64 + (y+1)² = 289
⇒ (y+1)² = 289 - 64 = 225
⇒ y+1 = +15 or -15
⇒ y = +15-1 or -15-1
⇒ y = 14 or -16

Thus, the point can be either (-15,14) or (-15,-16)

Hi there,

We can find the length x first since we are given the lengths of the other two sides of the bottom right triangle. In order to find the length of x, it is important to know the Pythagorean Theorem and the fact that x is the hypotenuse.

$a^{2}$ + $b^{2}$ = $c^{2}$ ← Pythagorean Theorem
