Answer:

I will say this idk if you learn by reading or watching better, so if it's reading then read on! but if it's watching then look up "how to graph lines" and there is a bunch of videos!

Step-by-step explanation:

so you have y = 3x - 2 so first on the y axis your start point will be (0, -2)

then refer to rise over run ( rise/run) where rise is up(on the y axis) and run is across on the x axis.

so you start at (o, -2) and up 3 points on the y axis and across 1 point (go left) and mark it and repeat( up 3 across 1) until you reach the top of the graph

then finish the graph so repeating this going to the bottom is the same but different directions:

so go back to (0, -2) and go down 3 points (y axis) and across 1 point(this time go right on the x axis) and repeat until you reach the bottom and then use the points you marked to trace a line and boom your done! (this explanation is only for number 10)

same rise over run but different points and possibly line direction.

so for number 11: your starting point is (0, 3) and you go up 4 point and across 1 point but this time go across to the right. repeat. once you at the top of the graph go back to (0, 3) and go down 4 points and 1 point to the left. repeat. until you reach the bottom. trace the line.

number 12: a bit more tricky. starting point is (0, 5) for this one you go up 6 points and across 5 to the right. repeat. until you get to the top then go back to (0, 5) and go down 6 points and across 5 to the left. repeat. once you reach the bottom trace your line. then done! Sorry to inform you I don't know about 13 and 14! :(

Bonus but still important: the reason why you are going left and right on some of the lines is because the + or - in your equations tell you which direction the line is facing, toward the left (on the top part of your graph) would be - and toward the right part of your would be a + in the equation

More Bonus: a formula Is y=mx + b (0, b)( for ex: 0,5) is the starting point and (mx or for ex 4x is the amount you go up and across. When there is a x that always means across 1 and when there is not a x (ex: 6/5) it's across whatever the 5 is. ex: 6/6 is up 6 and across 6

Hope this helps!

The table below shows a proportional relationship. True or False?

lana66690 [7]

According to the image, the table shows a relationship that is not proportional. First of all, you cannot multiply a number by 0 and get something other than 0. Anything multiplied by 0 is always 0.

Second, the rule is different for each row.

2x5=10

4x4=16

6x3.6=22

A proportional relationship must increase by the same amount, and this does not, which means it is not proportional.

the equation y=15x can be used to determine the amount of money y pauli's pizzeria makes by selling x pizzas . the graph shows t

abruzzese [7]

Answer:

Pauli's pizzeria make more money per pizza

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find out the slope of the graph of Leo's pizzeria

looking at the graph take the point (2,24)

The graph show a proportional relationship (the line passes through the origin)

The slope is m=y/x

we have

For x=2, y=24

substitute

m=24/2=$12 per pizza sold

The linear equation is

y=12x

step 2

Compare the slopes

<em>Pauli's pizzeria</em>

we have

y=15x -----> slope m=$15 per pizza sold

<em>Leo's pizzeria</em>

we have

y=12x -----> slope m=$12 per pizza sold

$15 per pizza sold > $12 per pizza sold

therefore

Pauli's pizzeria make more money per pizza
