Answer:

slope = - \frac{1}{2}

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - \frac{1}{2}(x - 2) ← is in point- slope form

with slope m = - \frac{1}{2}

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

7x - 15 = 4x - 12

3x - 15 = -12

3x = 3

x = 1

y = 7(1) - 15

y = 7 - 15

Which statement describes the function y=ax^n when a=1 and n is odd?
julsineya [31]
ANSWER

B. The graph is symmetric about the origin

EXPLANATION.

The given function is

y = a {x}^{n}

When a=1,

y = {x}^{n}

Let,

f(x)= {x}^{n}

f(-x)= {( - x)}^{n}

Since n is odd,

f(-x)=-{( x)}^{n}

\Rightarrow f(-x)=-f(x)

This implies that, the function

y={x}^{n}

is symmetric with respect to origin.

The correct answer is B
