Answer: The equation of the trend line is y = -2x + 24.

First, we need to find the slope. The slope is the change in y over the change in x between the points. Our points move down 4 units while moving right 2 units. So our slope would be -4/2 or just -2.

Second, we need to find the y-intercept. We are lucky because the y-intercept can be see clearly in the graph. It is (0, 24).

We can put the slope and y-intercept together to get the equation:
y = -2x + 24.

Dovator [93]

Answer:

The price of a medium pizza with 3 toppings is $15.

Step-by-step explanation:

If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)

So it will look like:

9+2(3)

Then you're gonna use PEMDAS, multiply 2*3

9+6

And then you get an answer of $15

Hope this helps :))

Which of the following coordinates exists on the line y = 3x + 1?

Natalija [7]

We are given

equation of line as

$y=3x+1$

we will check each options

option-A:

we can plug (3,1)

x=3 and y=1

$1=3*3+1$

$1=10$

we can see that

they are not equal

so, this is FALSE

option-B:

we can plug (-1,-2)

x=-1 and y=-2

$-2=3*-1+1$

$-2=-2$

we can see that

they are equal

so, this is TRUE

option-C:

we can plug (-3,4)

x=-3 and y=4

$4=3*-3+1$

$4=-8$

we can see that

they are not equal

so, this is FALSE

option-D:

we can plug (2,6)

x=2 and y=6

$6=3*2+1$

$6=7$

we can see that

they are not equal

so, this is FALSE
