Step-by-step explanation:

Hey there!

The given points are; (-4,-1) and (4,2).

Use slope formula.

$slope(m) = \frac{y2 - y1}{x2 - x1}$

Put all values.

$m = \frac{2 + 1}{4 + 4}$

Simplify it.

$m = \frac{3}{8}$

Therefore, the slope is 3/8.

Hope it helps...

Answer:

∠DCF = 129°

Step-by-step explanation:

We assume that line CE is between lines CD and CF.

The angle sum theorem applies:

∠DCF = ∠DCE +∠ECF

∠DCF = 75° +54°

∠DCF = 129°

Pythagoras theorem: leg 1 squared + leg 2 squared = hypotenuse squared

In the diagram, the triangle has angles 90 and 45. So the other angle in the triangle must be 45 degrees as well. (180 - 90 -45 = 45)

This means it is an isosceles triangle (since two angles are the same), so the two legs have the same length.

So we can say that length of leg1 = x, and the length of leg2 also equals x

Now let's use pythagoras' theorem:

leg1 = x

leg2 = x

hypotenuse = 16

x^2 + x^2 = 16^2

2x^2 = 16^2

2x^2 = 256

x^2 = 128

x = √(128)

x = 8√2

How is this a non proportional relationship y=2x 4?

saveliy_v [14]

Y=2x +4 is non proportional because b does not equal 0
The b in the equation is 4
As long as the y intercept is not more or less than 0, than it will be proportional
