The answer is that Y=4x-1
Brut [27]1 year ago
5 0

Answer: y = 4x-1

Step-by-step explanation:

1) Choose two points for the later equation.

For this example, I will use (-1,-5) and (2,7)

2) Place it in a rise/run equation. (y/x)

\frac{y2-y1}{x2-x1} \\\\\frac{7-(-5)}{2-(-1)} \\\\\frac{12}{3} \\\\4

The Slope is 4.

3) Find the y-intercept

So, we can place a given point and slope into a y=mx+b function.

y=4x+b

Next, we can substitute the point and slope.

7 = 4(2)+b\\7=8+b\\-1=b

4) Finally, place it all in slope intercept form

y = 4x-1

I need to find the table of -csc theta
AVprozaik [17]

See below for the table of -csc theta

<h3>How to determine the table?</h3>

The function is given as:

-csc theta

Rewrite properly as:

-\csc(\theta)

This is calculated as:

-\csc(\theta) = -\frac{1}{\sin(\theta)}

Set \theta to 0, 30, 45, 60 and 90

-\csc(0) = unde fined

-\csc(30) = -2

-\csc(45) = -\sqrt 2

-\csc(60) = -\frac{2\sqrt 3}{3}

-\csc(90) = -1

So, the table of -csc theta is

<u>Angle      -csc theta </u>

0              undefined

30            -2

45            -√2

60             -2/3 √3

90             -1
