Answer:

y=1/4+1

The y-intercept is 1.

When you plug in the numbers 8 and 3 in the correct spots from the equation, you should be able to get 3=3, which is true.

I first got this equation by starting out with y=1/4x

I then plugged in 8 in x and multiplied it with 1/4, getting the answer of 2.

What plus 2 equals 3? That answer is 1. So, y=1/4x+1

Hope I helped!

e-lub [12.9K]

Answer:

c. you reject a null hypothesis that is true

Step-by-step explanation:

We need to remember the following concepts

Error type I: Is an error associated to the probability of reject a null hypothesis when it is actually true

Error type II: Is an error associated of not rejecting a null hypothesis when the alternative hypothesis is the true

And the best answer for this case would be:

c. you reject a null hypothesis that is true

what �is the equation of a line that is perpendicular to the line y = − 2 5 x − 5 y = - 2 5 x - 5 and passes thr

Answer:

$y=\frac{1}{25}x-\frac{31}{25}$

Step-by-step explanation:

$y=-25x-5$

You can get the gradient of the line perpendicular to this as you know the products of their gradients will be -1.

$-25*m_{perpendicular}=-1\\m_{perpendicular}=\frac{1}{25}$

We have a gradient, and a point (6, 1), so we can now substitute our known values into the line equation.

$(y-y_0)=m(x-x_0)$

$y-1=\frac{1}{25} (x-6)$

Rearrange for y and collect terms.

$y=\frac{1}{25}x-\frac{6}{25}-1\\\\y=\frac{1}{25}x-\frac{31}{25}$
