<span>B) Reflect across x-->(-5, -2), reflect across y-->(-5, -2) ... nope </span>
<span>C) Translate 4 down -->(5,-2), rotate 180-->(-5, 2) ... nope </span>
<span>It must be D, but test just to be sure: </span>
<span>D) Reflect across x-->(-5, -2), rotate 90 counter-clockwise -->(2, -5) yes. 


</span><span>If you noticed that rotating B to be upright produced a mirror image of A, then you know that an odd number of reflections were involved and could eliminate answers B and C immediately.
</span>
Hope this helps

Which equation, in point-slope form, represents a line with m= -4/7 that goes through the point (-1, 4)?
Gelneren [198K]
A is the correct answer.

Point Slope Form: y - y₁ = m(x - x₁)

m = slope ⇒ -4/7
Coordinate: (-1  ,  4)
                       x₁    y₁

All you have to do is plug in all of the information above into the formula.

y - 4 = -4/7(x +1)

Thankyou for all the help
Travka [436]

Answer:

1. x + y = 180

2. x = 50 y= 130

Step-by-step explanation:

They're parallel.

We can label the unamed angle z.

So z = y

and 50 = x

There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.

x=50

so 50 + 50 = 100.

360 - 100 = 260

so 260 ÷ 2 = 130

y = 130 because y and z are equal so they're the same number
