Answer:

y = 2x + 11

Step-by-step explanation:

The point slope formula for a line is

y - y1 = m(x - x1)

We already have the slope, 2, and we can substitute the point (-4, 3) into (x1, y1):

y - 3 = 2(x + 4)

y - 3 = 2x + 8

y = 2x + 11

IgorLugansk [536]

Answer:

It allows to to know y-intercept formula which is used to graph a line.

Step-by-step explanation:

Y-intercept formula:

y=mx+b

M: slope (keep in fraction if it is fraction, to help you graph)

B: y-interecept

Find the distance between the two points rounding to the nearest tenth

mixas84 [53]

Answer:

8.54

Step-by-step explanation:

formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

$d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}$

$d=\sqrt{3^2 + 8^2}$

$d=\sqrt{9 + 64}$

$d=\sqrt{73}$

d= 8.54

Which polynomial function has a leading coefficient of 1 and roots 21 and 31 with multiplicity 1?

schepotkina [342]

Answer:

Which i think is the first one, there may just be a typing error.

Step-by-step explanation:

A polynomial of order n has the following format:

$f(x) = a(x - x_{0})(x - x_{1})...(x - x_{n-1})$

In which a is the leading coefficient, $x_{0}, x_{1},..., x_{n-1}$ are the roots.

If a root appears m times, they are said to have multiplicity m.

Leading coefficient of 1 and roots 21 and 31 with multiplicity 1

$f(x) = 1(x - 21)(x - 31)$

So the correct answer is:

$f(x) = 1(x - 21)(x - 31)$

Which i think is the first one, there may just be a typing error.
