-7x - 4y = -4 find the slope and y intercept of the line

Mathematics
1 answer:
ki77a [65]2 years ago
3 0

Answer:

The slope is -7/4 and the y intercept is 1

Step-by-step explanation:

-7x - 4y = -4

Put the equation in slope intercept form and solve for y

y = mx+b where m is the slope and b is the y intercept

Add 7x to each side

-7x - 4y+7x =+7x -4

- 4y =7x -4

Divide by -4

-4y/-4 = 7x/-4 -4/-4

y = -7/4 x +1

The slope is -7/4 and the y intercept is 1

Given the linear correlation coefficient r and the sample size n, determine the critical values of r and use your
Mila [183]

The critical value of r is mathematically given as r = +0.487, with no significant linear correlation. Option A.

<h3>What are the critical values of r?</h3>

Question Parameters

r = -0.868

n = 5

df = 5 - 2

df = 3

\alpha / 2 =0.025

Critical values r= \pm 0.878

Generally, there exists no linear correlation between the Critical values

as r=0.878

In conclusion,  Critical values: r = +0.487, no significant linear correlation
