Y = 6x - 4<br> y = -x + 3

likoan [24]

Answer:

(1, 2)

Step-by-step explanation:

Subtract the second equation from the first:

(y) -(y) = (6x -4) -(-x +3)

0 = 7x -7 . . . . . simplify

0 = x - 1 . . . . . . divide by 7

1 = x . . . . . . . . . add 1

y = -1 +3 = 2 . . . substitute into the second equation

The solution is (x, y) = (1, 2).

What is the equation of the line that passes through the points (−2, 1) and (1, 10)? 3x − y = −73x − y = −53x − y = 5x + 3y = −5

djyliett [7]

The two point formula :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The points are (-2, 1) and (1, 10)

Using the formula above :

$\begin{gathered} y-1=\frac{10-1}{1-(-2)}(x+2) \\ y-1=\frac{9}{3}(x+2) \\ y-1=3(x+2) \\ y-1=3x+6 \\ -3x+y=6+1 \\ -3x+y=7 \\ 3x-y=-7 \end{gathered}$

The answer is 3x - y = -7
