Graph the direct variation y=−1.5x. Using the graph, find the value of y corresponding to the value of x equal to 1; 0; 2; 3.

1 answer:

6 0

X=1
y=-1.5(1)
y=-1.5
(1,-1.5)

x=0
y=-1.5(0)
y=0
(0,0)

x=2
y=-1.5(2)
y=-3
(2,-3)

x=3
y=-1.5(3)
y=-4.5
(3,-4.5)

all you do is substitute the x value in the equation to get y

BRAINLIESTT ASAP! PLEASE HELP ME :)

Anvisha [2.4K]

Step-by-step explanation:

$\displaystyle y = Asec(Bx - C) + D$

According to this trigonometric function, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:

$\displaystyle Phase\:[Horisontal]\:Shift → \frac{0}{4} = 0 \\ Period → \frac{2}{4}π = \frac{π}{2}$

Therefore we have our answer.

Extended Information on the trigonometric function

$\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{2}{B}π \\ Amplitude → |A|$

NOTE: Sometimes, your vertical shift might tell you to shift your graph below or above the midline where the amplitude is. Moreover, ALL tangent, secant, cosecant, and cotangent functions have NO AMPLITUDE.

I am joyous to assist you anytime.

Write the equation of the line that passes through (-4,3) and is parallel to y = -2x - 8.

kobusy [5.1K]

Answer:

y = -2x - 5

Step-by-step explanation:

Let the equation if the line be y = mx + c

since the line is parallel to y = -2x - 8, their gradients/slope must be the same (aka m = -2)

sub (-4, 3):

3 = -2(-4) + c

c = -5

therefore, the equation of the line is y = -2x - 5

This is a question on coordinate geometry. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
