Question

Solve graphing.

Answer 1

\[y = - \frac{ 3 }{ 2}x + 4\]

How would I solve that? How would I do the Rise over Run when my fraction is negative?

Answer 3

Answer 4

Graph the first three points, then draw a line through them

Answer 5

HOw would I graph the fraction part?

Answer 6

You're focusing too much on the "fraction part". What you will be graphing are points on a line.

Answer 7

Remember, you still have y = mx + b, which is the formula for a line. The fraction part only represents the slope of the line.

Answer 8

Huh? What do you mean?

Answer 9

My school is telling me that I would graph (0, 4) and then graph the fraction with rise over run, but the fraction is negative and I don't know how to work with it.

Answer 10

Just focus on graphing the points.

Answer 11

Focus on the x and y intercepts

Answer 12

I don't understand.

Answer 13

Wouldn't I graph 4?

Answer 14

You found one of the points: (0,4)

Answer 15

Now find the x-intercept. Set y = 0, then solve for x

Answer 16

Uhhh..

Answer 17

Do you have any clue what's going on here?

Answer 18

I'm left with a fraction still. I don't know how to graph that fraction.

I know it would be an rise over run process, but the fraction is negative. That changes it for me.

Answer 19

What you need to graph is a straight line and the most important parts relating to it such as the x and y intercepts if they are any, in this case there are both.

Answer 20

What happens when the fraction is negative? Does it change? Would I make the 3 negative? Would both the numbers be negative?

Answer 21

I'm not graphing both the intercepts. It says graph the y-intercept first, and graph the slope, which is the fraction?

Answer 22

just the 3 is negative.

Answer 23

When you graph the two intercepts and connect them, it will automatically contain the slope/gradient of the line.

Answer 24

so (-3, 2)

Answer 25

\[y = - \frac{ 3 }{ 2}x + 4\]
\[0 = - \frac{ 3 }{ 2}x + 4\]
\[\frac{ 3 }{ 2}x = 4\]
\[\frac{ 3x }{ 2} = 4\]
\[3x = 8\]
\[x = \frac{8}{3}\]
\[x = 2\frac{2}{3}\]

Answer 26

Slope/gradient is found by \[M = \frac{y2-y1}{x2-x1}\] or rise/run
your rise is -3 and run is 2

Answer 27

So the other point is \[(2.67, 0)\]

Answer 28

I think it just wants one answer .-.

Answer 29

This is basic 9th grade math.

Answer 30

No, you need at least two points to graph a line. You can't graph a line with only one point.

Answer 31

Didn't your teacher go over this with you?

Answer 32

I mean, I think they want me to find the rise over run by graphing (-3, 2) and 4.

Answer 33

You already have the rise over run

Answer 34

-3/4 is the rise over run

Answer 35

So:

\[-\frac{ 3 }{ 2 } = \frac{ -3 }{ 2 }\] Is this correct? When dealing with a negative fraction in rise over run, the top number becomes negative when putting it into an ordered pair?

Answer 36

?

Answer 37

Ask your teacher about it. You are too confused.
