Do the points A(1,3) B(4,2) C(-2,4) lie on the same line? Explain your answer. Show all work.

We can see that

$Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC$

The given points are on same line.

Further explanation:

There are two methods to find if the given points are on same line

The slope method: If the points are on same line the slopes of two pairs of points will be same
Area of triangle method

Given points are:

A(1,3) B(4,2) C(-2,4)

We will find the slope of AB, BC, and AC

So,

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

$Slope\ of\ AB=\frac{2-3}{4-1} \\=-\frac{1}{3}$

$Slope\ of\ BC=\frac{4-2}{-2-4}\\ =\frac{2}{-6}\\=-\frac{1}{3}$

$Slope\ of\ AC= \frac{4-3}{-2-1} \\=-\frac{1}{3}$

We can see that

$Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC$

The given points are on same line.

Can you answer this quickly please

Answer:

Question 5.

a) 118°

b) 131°

Step-by-step explanation:

<u>Part a:</u>

I'm sorry I find it tricky to explain this, you would get more confused than you are now.

<u>Part b:</u>

All four interior angles of a quadrilateral are equal to 360° so

75°+ 86°+ 68°+m°= 360°

229° +m° = 360°

m°= 360°-229°

m°= 131°
