I NEED HELP ASAPP!!!

Llana [10]

Answer:

Step-by-step explanation:

$x - 2y = -8 \\y = 5x-2$

$x - 2 y = - 8$

add -x to both sides

$x - 2y - x = -8 - x \\- 2y = -8 - x$

multiply both sides by -1/2

$-2y * (\frac{-1}{2} ) = (-8-x) (\frac{-1}{2} )$

$y = 4 + \frac{x}{2} \\y = \frac{x}{2} + 4$

the equations don't have the same slope so they aren't parallel

The solpes product doesn't equal -1 so they aren't perpendicular

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form. (2,8), and (8,2)

leonid [27]

Answer:

$y=-x+10$

Step-by-step explanation:

Hi there!

Slope intercept form: $y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

<u>1) Find the slope (m)</u>

$m=\frac{y_2-y_1}{x_2-x_1}$ where the two given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the given points (2,8),and (8,2)

$m=\frac{2-8}{8-2}\\m=\frac{-6}{6}\\m=-1$

Therefore, the slope of the line is -1. Plug this into $y=mx+b$ :

$y=-x+b$

<u>2) Find the y-intercept (b)</u>

$y=-x+b$

Plug in a given point and solve for b

$8=-2+b$

Add 2 to both sides

$8+2=-2+b+2\\10=b$

Therefore, the y-intercept is 10. Plug this back into $y=-x+b$ :

$y=-x+10$

I hope this helps!
