If a straight line passes through the point X=8 and Y=5 and also through the point X=11 and Y=15, what is the slope of this line? If your answer is a fraction, round to two decimal places.
Question 2
Suppose that on average there are four more car accidents for every extra inch of snowfall in Pennsylvania. If snowfall is the variable on the Y-axis and car accidents is the variable on the X-axis, then if we graph this relationship, what is the slope of the line? If your answer is a fraction, round to two decimal places.
Question 3
Given a linear relationship, if the value on the Y-axis changes from 44 to 37 when the value on the X-axis changes from 21 to 24, then what is the slope of the line? If your answer is a fraction, round to two decimal places.
Question 4
Suppose you are given the equation Y = 16 + 3X. If Y is on the vertical axis and X is on the horizontal axis, then what is the slope?
Question 5
Suppose you are given the equation Y = 6 – 0.7X. If Y is on the vertical axis and X is on the horizontal axis, then what is the vertical intercept?
Question 6
Suppose you are given the equation X = 6 – 1Y. If Y is on the vertical axis and X is on the horizontal axis, then what is the slope? If your answer is a fraction, round to two decimal places.
Question 7
Suppose you are given the equation X = 22 – 4Y. If Y is on the vertical axis and X is on the horizontal axis, then what is the vertical intercept? If your answer is a fraction, round to two decimal places.
Question 8
Suppose you are given the equation Y = 8 + 3X. If X is equal to 7, what is the value of Y?
Question 9
Suppose you are given the equation Y = 24 – 3X. If Y is equal to 16, what is the value of X? If your answer is a fraction, round to two decimal places.
Question 10
Suppose you own a cupcake shop and have gathered data on the number of cupcakes you sell each month at different prices. This data is represented in the table below:
Prices for Cupcakes
Price Number of Cupcakes Sold
$2 50
$4 40
$6 30
Assuming a linear relationship, if you were to raise your price to $8 next month, how many cupcakes could you expect to sell?
