To Find:The x- and y-intercepts of each linear function.
Answer to Problem 5CYU
The required answer is:
Explanation of Solution
Given information:
Solution:
To find the x- intercept, look for the point where the line crosses the x-axis.
In the above graph the line crosses at
Therefore the x- intercept is 25, because it is the x-coordinate of the point where the line crosses the x-axis.
The x-intercept 25 means after 25 minutes, the temperature is at 0 degree Fahrenheit.
To find the y- intercept, look for the point where the line crosses the y-axis.
In the above graph the line crosses at
Therefore the y- intercept is -4, because it is the y-coordinate of the point where the line crosses the y-axis.
The y-intercept -4 means that the temperature is at -4 degree Fahrenheit at time 0.
