To graph a rate or ratio from a table, how do you determine the scales to use on each axis

1 answer:

8 0

First determine how much room you have for each axis. Let's say you count your graph paper and it has 30 squares by 10 squares.

Then find the largest number in the x-values. If you want your graph long-ways, then plot the x-values on the longer length of the sheet, the side with 30 squares.
Let's say your largest x-value is 300. Then you divide that largest value (300) by how many squares are on the axis (30).
300/30 = 10, so each square is 10.

Same thing goes for the y-axis. Say your largest y-value is 50. If the y-axis of your graph paper is 10 squares long, then each square would increase by
50/10 = 5.

Aloiza [94]

Answer: x=−1 or x=1 or x=−2 or x=3

Step-by-step explanation: Step 1: Factor left side of equation.

(x+1)(x−1)(x+2)(x−3)=0

Step 2: Set factors equal to 0.

x+1=0 or x−1=0 or x+2=0 or x−3=0

x=−1 or x=1 or x=−2 or x=3

Graphing/Slopes (Easy points!!) (ASAP) (URGENT) (Please check my other questions)<br><br>

spin [16.1K]

Answer:

The statement is incorrect because an inverse relationship between y and x would imply that the graph would be a downward curved graph whose slope changes rather than linear which has constant slope (see image).

Best to express this situation as:
There is a linear relationship between y and x with a negative constant slope. The keyword here is constant since the slope is the same in a linear relationship

Step-by-step explanation:

An inverse relationship exists between y and x when y is proportional to the reciprocal of y

This would be expressed in the form $y$ ∝ $\frac{1}{x}$

As x decreases , y increases or vice-versa. It is often expressed in equation form as $y=\frac{k}{x}$ or $y = kx^{-1}$ where k is a constant and whose graph is curved in nature. The slope is changing for the range of x values not constant as would be the case for a linear graph

All we can say about the data is that there is a linear relationship between y and x with a negative constant slope
