Question

Help with four algebra questions? Will Medal and Fan.

Answer 1

a. y = -x - 3
b. y = x - 3
c. y = 2x - 3
d. y = -2x + 3

Answer 2

In a relationship between two variables, what is the variable called that changes in response to another variable?
a. function
b. input function
c. independent variable
d. dependent variable

Answer 3

what is the equation for slope? if you can tell me that, you can use that equation with any 2 points to get the slope

Answer 4

Is it for a slope? or just a normal equation? :)

Answer 5

Question 2?

Answer 6

the first one

Answer 7

oh sorry i'm talking about the first one, if you can find the slope of the line whose points are given in the table, you're on the way to the right answer

Answer 8

It just says "Which equation represents the relationship shown in the table"

Answer 9

oh, you mean that way

Answer 10

don't you just put the x and the y values in their position? Or it's different?

Answer 11

you can substitute individual values of x and y and find which one it works for in all option given

Answer 12

yes, that is true too :)

Answer 13

here's a real life example for question 2: assume that x is a gas pedal, and y is the speed of the car. if you press the gas pedal you increase the speed of the car y right?

Answer 14

generally speaking x is regarded as the independent variable, because it is able to be independently changed, while y is the dependent variable, it relies on x to have a valuel

Answer 15

oh @Mariam.A you can just plug and chug values into each given equatino too for question 1

Answer 16

@3abf6277 so it would be dependent variable?

Answer 17

indeed, that variable can ONLY be changed by changing another, usually x

Answer 18

@iogenmrfngpg yeah, it should work just make sure your RHS is equal to the LHS

Answer 19

Okay so for the first one what all should I do? I'm a little confused about it.

Answer 20

I would take the first 2 points in the table and calculate the slope between them. and using point slope form equation, plug and chug any point into that equation to get b

Answer 21

ok so use individual values of x and y
so for the first equation which the formula is y=-x-3
and your values are (0,-3)
which means when x=0 y=-3

Answer 22

so in the equation
y=-x-3
-3=-0-3
-3=-3
so both sides are equal

Answer 23

but confirm this by using another value (1,-1)
so y=-x-3
-1=-(1)-3
-1=-4
so both sides are not equal

Answer 24

therefore the first equation is not an option
try doing the same thing for the next equation an see if there is any consistencies

Answer 25

do u get my explanation @iogenmrfngpg
