Answer:

y = -2x + 6 and y = 1/3x - 7

Step-by-step explanation:

For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:

y = -2x + 6

The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:

y = 1/3x - 7

Solve for y.<br> 8+4y= -8

Andrew [12]

Answer:

-4

Step-by-step explanation:

8+4y= -8

4y= -8 -8

4y= -16

divide both sides by the coeffient of the variable. in this case divide both sides by 4

y=-4

Answer:

Option A is correct.

$\sin \frac{\pi}{3}=\frac{opposite}{Hypotenuse}=\frac{opposite}{1}=opposite$

The length opposite the angle is the vertical distance from the x-axis on the graph

Step-by-step explanation:

Given:

Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.

The angle $\frac{\pi}{3}$ forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).

Also, the terminal side intersect the circle at (x, y).

Now, to find the value of $\sin \frac{\pi}{3}$ ,we will use the trigonometric ratios formulas :

For any right angle, $Sine = \frac{opposite}{Hypotenuse}$

Here, hypotenuse = r =1 and the side opposite the angle $\frac{\pi}{3}$ is also called the vertical distance from the x-axis.

therefore, $\sin \frac{\pi}{3} =\frac{opposite}{Hypotenuse}=\frac{opposite}{1}=opposite$

Also, the length opposite the angle is the vertical distance from the x-axis on the graph
