Answer:

The slopes of line segments AC and AD are same or constant i.e $\frac{1}{3}$

Step-by-step explanation:

We need to find slopes of AC and AD and tell if they are same or not.

The formula used to calculate slope is: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Finding slope of AC

We have A=(3,2) and C=(0,1)

Finding slope using formula:

We have $x_1=3, y_1=2, x_2=0,y_2=1$

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-2}{0-3}\\Slope=\frac{-1}{-3}\\Slope=\frac{1}{3}$

So, Slope of AC is $\frac{1}{3}$

Finding slope of AD

We have A=(3,2) and C=(9,4)

Finding slope using formula:

We have $x_1=3, y_1=2, x_2=9,y_2=4$

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4-2}{9-3}\\Slope=\frac{2}{6}\\Slope=\frac{1}{3}$

So, Slope of AD is $\frac{1}{3}$

So, the slopes of line segments AC and AD are same or constant i.e $\frac{1}{3}$

Which set of rational numbers are orders from least to greatest? A) -1, -1 1/2, -1 1/4, -1 7/8 B)-1 7/8, -1 1/2, -1 1/4, -1

Semmy [17]

Answer:

-1 7/8, -1 1/2, -1 1/4, -1

Step-by-step explanation:

First note that the negative value closer to zero on the number is greater. an those far from zero will be the least

According to the given option, we can first express the fractions as percentage as shown

-1 7/8 = -15/8 * 100 = -187.5%

-1 1/2 = -3/2 * 100 = -150%

-1 1/4 = -5/4 * 100 = -125%

-1 = -1 * 100 = -100%

Based on the explanation above, the least value is -187.5% and the greatest value is -100%

Rearranging from least to greatest is expressed as -187.5%,-150%, -125%, -100%

According to their respective fractions;

-1 7/8, -1 1/2, -1 1/4, -1
