Do the three points lie on one line?

padilas [110]

Answer:

Yes. No graph paper.

Step-by-step explanation:

Let's say the 3 points are A, B, C.

If A, B and C lie on one line then $m_{AB} = m_{BC} = m_{AC}$

$m_{AB} = \frac{y_{B}-y_{A} }{x_{B}-x_{A}} = \frac{2-6}{3-5} = \frac{-4}{-2} = 2\\m_{BC} = \frac{y_{C}-y_{B} }{x_{C}-x_{B}} = \frac{8-2}{6-3} = \frac{6}{3} = 2\\\\m_{AC} = \frac{y_{C}-y_{A} }{x_{C}-x_{A}} = \frac{8-6}{6-5} = \frac{2}{1} = 2\\\\$

Hence, they lie on one line.

You don't need to use a graph paper to prove it.

Find the value of 'x' in the given figure

Archy [21]

$\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}$

(2x-20)°+(x+65)°=180°

2x-20+x+65=180

3x+45=180

3x=180-45

3x=135

x=135/3

x=45°

Witch equation dose the graph below represent

fenix001 [56]

When the function goes 1 to the right, it goes 2 down. Therefore the direction of the function is
$\frac{-2}{ 1} = - \frac{2}{1}$
Hence, the function represented is
y = -2x
