Determine the intercepts of the line that passes through the following points. (-10,-28) , (-6,-21) , ( -2,-14)

1 answer:

8 0

The line through (a,b) and (c,d) is

(c-a)(y-b) = (d-b)(x-a)

Picking the last two points,

(-2 - -6)(y - -21) = (-14 - -21)(x - -6)

4(y+21) = 7(x+6)

When x=0

4y + 84 = 42

4y = -42

y = -21/2

Answer: -21/2

We never used the first point, let's check it's on the line

4(y+21) = 7(x+2)

4(-28 + 21) = -28

7(-10 + 6) = -28, good

Answer:

Scatterplot

Step-by-step explanation:

Bivariate data means that the data is in two variables. For example, if the height of the students is plotted against their age, this data will be the bivariate data.

A bivariate data is represented using the graph known as Scatter Plot. One variable is plotted along x-axis and second variable is plotted against y-axis. After plotting the two variables we can observe the relation(association) between the two variable using the line of best-fit which models the relation between the two variables.

So, the answer to this question is Scatterplot.

For this case we have to define root properties:

$\sqrt [n] {a ^ n} = a ^ {\frac {n} {n}} = a$

In addition, we know that:

$a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}$

On the other hand:

$4 ^ 2 = 16$

Thus, we can rewrite the given expression as:

$\sqrt {4 ^ 2 * a ^ 8 * \frac {1} {b ^ 2}} =\\4 ^ {\frac {2} {2}} * a ^ {\frac {8} {2}} * \frac {1} {b ^ {\frac {2} {2}}} =\\4 * a ^ 4 * \frac {1} {b}$
