Write equation in slope-intercept form for the line described.

Answer to Problem 51SR
Explanation of Solution
Given information:
Write equation in slope-intercept form for the line described.
Passes through
Calculation:
Point- slope form:
The point −slope form of the equation of a line is
Parallel lines:
Two nonvertical lines are parallel if and only if they have the same slope all vertical lines are parallel.
Consider the following set of condition;
Pass through
First find the slope of the line.
Here, the slope of the line is
Since lines that are parallel have the same slope, so the slope of the line parallel to given line is
Now, use the point-slope form and ordered pair
Apply distributive property and simplify;
Hence, the equation of line is

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
