Indicate in standard form the equation of the line passing through the given points, writing the answer in the equation

Kryger [21]

Answer:

$y + x - 6 = 0$

Step-by-step explanation:

Given

$M(0,6) \ and \ N(6,0)$

Required

Find the equation of the line

First, the slope of the line has to be calculated using the following formula;

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

$where\ (x_1,y_1) = (0,6) \ and \ (x_2,y_2) = (6,0)$

So, the equation becomes

$m = \frac{0 - 6}{6 - 0}$

$m = \frac{-6}{6}$

$m = -1$

The equation of the line can then be calculated using

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

$Using \ m = \frac{y - y_1}{x - x_1}$

$-1 = \frac{y - 6}{x -0}$

$-1 = \frac{y - 6}{x}$

Multiply both sides by x

$-1 * x = \frac{y - 6}{x} * x$

$-x = y - 6$

Add x to both sides

$x -x = y - 6 + x$

$0 = y - 6 + x$

Reorder

$y + x- 6 = 0$

$Using \ m = \frac{y - y_2}{x - x_2}$

$-1 = \frac{y - 0}{x - 6}$

$-1 = \frac{y}{x - 6}$

Multiply both sides by x - 6

$-1 * (x-6) = \frac{y}{x - 6} * (x-6)$

$-1 * (x-6) = y$

$-x+6 = y$

Add x - 6 to both sided

$x - 6 -x+6 = y +x - 6$

$0 = y + x - 6$

$y + x - 6 = 0$

Hence, the equation of the line is $y + x - 6 = 0$

Y = - x2 + 1 and y = x2. At which approximate points are the two equations equal?

bazaltina [42]

Answer:

see explanation

Step-by-step explanation:

given the 2 equations

y = - x² + 1 → (1)

y = x² → (2)

Substitute y = x² into (1)

x² = - x² + 1 ( add x² to both sides )

2x² = 1 ( divide both sides by 2 )

x² = $\frac{1}{2}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{1}{2} }$ = ± $\frac{1}{\sqrt{2} }$

Substitute these values into (2) for corresponding values of y

x = $\frac{1}{\sqrt{2} }$ ⇒ y = ( $\frac{1}{\sqrt{2} }$ )² = $\frac{1}{2}$

x = - $\frac{1}{\sqrt{2} }$ ⇒ y = (- $\frac{1}{\sqrt{2} }$ )² = $\frac{1}{2}$

The points are ( ± $\frac{1}{\sqrt{2} }$ , $\frac{1}{2}$ )
