Well, don't you already have the t value ,-7.

(5,-7) m= -3

It's ironic that we're learning the same thing.

First you will need to put the information into point-slope form [y-y1=m(x-x1)]

1. y is y and y1 is the y-value in the ordered pair. m is the slope. x is x and x1 is the x-value in the ordered pair.

y-(-7)=-3(x-5)

2. Solve

y+7=-3x+15
-7 -7
_________
y=-3x+8

3. Now it is in slope-intercept form.

4. The y-intercept is 8 on the graph and y=-3x+8

What is the y-intercept of the line represented by the equation?<br><br><br><br> y = –6x – 1
ValentinkaMS [17]
If the equation of a line is written in the y=mx+b form, b is the y-intercept.

y=-6x-1 \\&#10;b=-1

The y-intercept is -1. The line crosses the y-axis at the point (0,-1).

"Trigonometric Models" (50 POINTS)<br> Is my graph right?
ch4aika [34]

Answer:

Yes, this graph is absolutely right for the function y = 2\sin(2x)-3.

Step-by-step explanation:

firstly we will calculate amplitude, period, phase shift, and vertical shift.

Use the standard form a\sin(bx-c)+d to calculate the values of amplitude, period, phase shift, vertical shift.

here a = 2

     b = 2

     c = 0

    d = -3

Amplitude = |a|  = 2

period = \frac{2\pi}{|b|}

           = \frac{2\pi}{2} = \pi

phase shift = \frac{c}{b} = 0

and vertical shift = d = -3

so, by using this information, if we plot the graph then the graph obtained will be same as the given graph.
