Anestetic [448]

Use Pythagorean theorem,   C^2 = A^2 + B^2

Where c is the hypotenuse, and b and a are the sides.

Substitute and solve:

C^2 = 6^2 + 8^2

C^2 = 36 + 64

C^2 = 100

\sqrt{C^2} = \sqrt{100}

C = 10

What is the equation of the line that is parallel to Y =-2/3 X +4 and that passes through (-2,-2)?
kvv77 [185]

Answer:

y=-\frac{2}{3}x-\frac{10}{3}

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

  • Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0)
  • Parallel lines always have the same slope

<u>1) Determine the slope (m)</u>

y =-\frac{2}{3}  x +4

In the given equation, -\frac{2}{3} is in the place of m, making it the slope. Because parallel lines always have the same slope, the slope of the line we're currently solving for is -\frac{2}{3}. Plug this into y=mx+b:

y=-\frac{2}{3}x+b

<u>2) Determine the y-intercept (b)</u>

y=-\frac{2}{3}x+b

Plug in the given point (-2,-2) to solve for b

-2=-\frac{2}{3}(-2)+b\\-2=\frac{4}{3}+b

Subtract \frac{4}{3} from both sides to isolate b

-2-\frac{4}{3}=\frac{4}{3}+b-\frac{4}{3}\\-\frac{10}{3} =b

Therefore, the y-intercept of the line is -\frac{10}{3}. Plug this back into y=-\frac{2}{3}x+b:

y=-\frac{2}{3}x-\frac{10}{3}

I hope this helps!
