Given information
Given that, the price of a single issue of stock can fluctuate throughout the day. A linear equation that represents the price of the stock for Shipment Express is y = 15 – 1.5x where x is the number of hours passed in an eight-hour day of trading.
Then we have to identify the slope and y-intercept and interpret their meaning.
Step-by-step explanation
Step 1.
The standard form of the linear equation is y = a + bx where a is the y-intercept and b is the slope.
And it is given that y = 15 – 1.5x where y-intercept a=15 and the slope b=-1.5.
The slope is -1.5 means the stock is losing value at a rate of $1.50 per hour and the y-intercept is $15 means the price of the stock before the trading day began was $15.
