What are the slope and the y-intercept of the linear function that is represented by the table? x y –1 Negative three-halves Neg

MAVERICK [17]

Answer:

The slope of the line is 3 and the y-intercept is (3/2) three-halves.

Step-by-step explanation:

The data provided is:

X Y

-1.0 -1.5

-0.5 0.0

0.0 1.5

0.5 3.0

The slope of the linear function is denoted by, b and the intercept is denoted by, a.

The formula to compute the slope and intercept are:

$a &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} \\\\b &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2}$

Compute the values required in Excel.

Compute the slope and intercept as follows:

$a &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 3 \cdot 1.5 - (-1) \cdot 3}{ 4 \cdot 1.5 - (-1)^2} \approx \frac{3}{2} \\ \\b &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 4 \cdot 3 - (-1) \cdot 3 }{ 4 \cdot 1.5 - \left( -1 \right)^2} \approx 3\end{aligned}$

Thus, the slope of the line is 3 and the y-intercept is (3/2) three-halves.

Can someone answer questions 2 - 7 for me please?

MrRissso [65]

Question No.2

speed= distance/ time

1200km/0.006s= 200 000 km/s

Question 4

wavelength = wavespeed / frequency

wavespeed = 16/8 = 2

Question 5

(400/60s) = 6.6667 waves/ sec (Hz).
Velocity = 0.008m/sec. 
Wavelength = (v/f) = 0.008/6.6667 = 0.0012 metre (1.2mm).
