Answer:

$y - 4x = 1$

Step-by-step explanation:

Given

$(x_1,y_1) = (1,5)$

$(x_2,y_2) = (3,13)$

Required

The equation of the line

Back up:

First, calculate the slope(m)

$m = \frac{y_2 -y_1}{x_2 - x_1}$

$m = \frac{13-5}{3-1}$

$m = \frac{8}{2}$

$m = 4$

Calculate the area using:

$y - y_1 = m(x - x_1)$

$y- 5 = 4(x - 1)$

$y- 5 = 4x - 4$

Collect Like Terms

$y - 4x = 5 - 4$

$y - 4x = 1$

Solve the systems by the addition method: {x-2y = -4 2x + y = 7

Klio2033 [76]

Answer:

(2, 3 )

Step-by-step explanation:

Given the 2 equations

x - 2y = - 4 → (1)

2x + y = 7 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

4x + 2y = 14 → (3)

Add (1) and (3) term by term to eliminate y, that is

5x = 10 ( divide both sides by 5 )

x = 2

Substitute x = 2 into either of the 2 equations and evaluate for y

Substituting into (2)

2(2) + y = 7

4 + y = 7 ( subtract 4 from both sides )

y = 3

Solution is (2, 3 )
