Step-by-step explanation:
Given that:
Temperature at 7 PM last night =
Temperature at 7 AM the next morning =
a. The change in temperature from 7 PM to 8 AM = Temperature at 7 AM - Temperature at 7 PM
Negative sign indicates that the temperature has decreased.
b. Change in temperature each hour:
Divide the Change in temperature with the number of hours.
Negative sign indicates that the temperature has decreased.
Answer (<u>assuming it can be written in slope-intercept form)</u>:
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, . Substitute the x and y values of the given points into the formula and solve:
So, the slope is .
2) Now, use the point-slope formula to write the equation of the line. Substitute
,
, and
for real values.
Since represents the slope, substitute
for it. Since
and
represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form (
format) and find the following answer:
