Answer:

Step-by-step explanation:

Given the regression equation :

y=2+3x

Mean of y values ; y = 5.0

Where y is the predicted variable ; x = predictor variable

The predicted value of y for X = 2

Null: H0 = 5

Alternative H1 : ≠ 5

What is the slope of 6x+10y=8<br> (choice A)<br> A -3/4<br><br> B -5/4<br><br> C -3/5<br><br> D -4/5
kvv77 [185]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 6x + 10y = 8 into this form by subtracting 6x from both sides

10y = - 6x + 8 ( divide all terms by 10 )

y = - \frac{3}{5} x + \frac{4}{5} ← in slope- intercept form

with slope m = - \frac{3}{5} → C
