Question 475109: Find an equation of the line having given the slope and containing the given point. m=-6,(5,8). The equation of the line is y=______? I also need to know how to figure the function w(d)= 0.112d approximates the amount of centimeters of water that results from melting snow. Find the amount of water that will result from snow melting from depths of 19 cm, 22 cm, and 50cm.

You can put this solution on YOUR website! Find an equation of the line having given the slope and containing the given point. m=-6,(5,8)
-----------------------
Here's one I just did.
Only the numbers are different.
-------------------------
Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form.
-------------
y = –x + 6 is in slope-intercept form, y = mx + b, where m = slope and b = the y-intercept.
----------
The slope of y = –x + 6 is -1
Parallel lines have the same slope, so the line thru (-4,2) will have a slope of -1 also.
Use y = mx + b and the point to find b
2 = -1*(-4) + b
b = -2
-------
--> y = -x - 2
----------------------------------------------
I also need to know how to figure the function w(d)= 0.112d approximates the amount of centimeters of water that results from melting snow. Find the amount of water that will result from snow melting from depths of 19 cm, 22 cm, and 50cm.
W(19) = 0.112*19 = 2.128 cm of water
Multiply the others the same way.
