Please provide the graph or specific details so that I can write the equation for it.
Tell whether the pair of lines are parallel, perpendicular, or neither. y = 3/4x + 7 and 4x - 3y = 9 (1 point) The lines are
To determine the relationship between these two lines, we need to examine the slopes of each line.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line.
For the first line y = 3/4x + 7, the slope is 3/4.
For the second line 4x - 3y = 9, we need to rewrite it in slope-intercept form. First, we move the term containing x to the other side, and divide by -3 to isolate y:
-3y = -4x + 9
y = 4/3x - 3
The slope of the second line is 4/3.
Since the slopes are negative reciprocals of each other (3/4 and -4/3), the two lines are perpendicular to each other.

Does the graph have a positive correlation, negative correlation, or neither? (1 point)
To determine if the graph has a positive or negative correlation, we need to look at the slope of the graph. If the slope is positive, the correlation is positive; if the slope is negative, the correlation is negative.
Since we are not given the graph or any specific data points, we're unable to determine the correlation without more information.

A. Find the equation of the line of best fit for the given table. (Round to the nearest tenths place.) B. Use the equation to estimate the stopping distance at 90 mi/h. (2 points) A. y= B.
I'm sorry, but you haven't provided the table or the data points for me to calculate the equation of the line of best fit. Please provide the data points or more information so that I can assist you with calculating the equation and estimating the stopping distance at 90 mph. Thank you.
Polar bears are listed as a threatened species. In 2005, there were about 25,000 polar bears in the world. If the number of polar bears declines by 1000 each year, in what year will polar bears become extinct?(2 points) a.) What equation models the number of polar bears? How can graphing the equation help you solve the problem?
To model the number of polar bears over time, we can use a linear equation. The initial population of polar bears in 2005 was 25,000. Given that the number of polar bears declines by 1000 each year, we can express this relationship using the following equation:
Number of polar bears = 25,000 - 1000*(Number of years since 2005)
This equation represents the population of polar bears at any given year, considering the initial population of 25,000 and the decline of 1000 polar bears per year.
Graphing this equation will help identify the year in which the population of polar bears becomes zero, indicating the year when they will become extinct. By plotting the equation and finding the x-intercept (where the population is zero), we can determine the year in which polar bears are projected to become extinct.
Number of polar bears = 25,000 - 1000*(Number of years since 2005)
