What is the slope-intercept equation of the line going through (3, -6) and
jok3333 [9.3K]

Hi there!

\large\boxed{D. \text{ }y = -4x + 6}

To derive an equation given the points, we can use the slope formula:

slope = \frac{y_{2}-y_{1}}{x_{2}-x{1}}

Plug in the corresponding coordinates:

slope = \frac{-6-2}{3-1}

Simplify:

slope = \frac{-8}{2} = -4

Therefore, we have:

y = -4x + b

Plug in the x and y values for a coordinate to solve for b:

2 = -4(1) + b

2 = -4 + b

b = 6

The equation is:

y = -4x + 6. The correct answer is D.

The coordinates of A are ( 2, -5)

When it's reflected in the y axis it becomes

( - 2 , - 5)

Hope this helps you

Solve: 2 + = 2. Give solutions in interval [0, 2)
Dovator [93]
\because\cos 2x+\sin x=\sin 2x\because\sin 2x=2\sin xcosx\because\cos 2x=\cos ^2x-\sin ^2x

→ Substitute cos 2x and sin 2x by their expressions

\therefore\cos ^2x-\sin ^2+\sin x=2\sin x\cos x

→ Subtract both sides by sin x

\cos ^2x-\sin ^2x=2\sin xcosx-\sin x

→ Take sin x as a common factor in the right side

\therefore\cos ^2x-\sin ^2x=\sin x(2\cos x-1)

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs

Contains fractions <br> 6v-5/8=7/8
Novay_Z [31]

Answer: v = 2

Step-by-step explanation:

Your equation:

\frac{6v-5}{8}  = \frac{7}{8}

You can multiply both sides by 8 to eliminate the fraction, which gives you this:

6v - 5 = 7

Then, you can solve for it:

6v = 12

v = 2
