Sometime you have to convert medicine amounts or maybe how much you have to cut something in surgery that you have to convert you also might use percentages figuring out the percent of something to go in a specific medication
d. y = 3/4x + 17/4.
To write the slope-intercept form y = mx + b of a line passing through (-3, 2) and (1,5).
First, we have to calculate the slope m.
m = (y₂-y₁)/(x₂-x₁), with (x₁, y₁) = (-3, 2) and (x₂, y₂) = (1, 5)
m = (5 - 2)/(1 - (-3))
m = 3/4
Second, we have to find the y-intercept.
y = mx + b, where m is the slope and b is the y-intercept.
Using one of the two ordered pair and plug it in for x and y in the equation y = mx + b.
Taking the ordered pair (1, 5):
5 = 3/4 (1) + b
5 = 3/4 + b
Solving for b
b = 5 - 3/4
b = [5(4) - 3(1)]/4
b = (20 - 3)/4
b = 17/4
Finally, write down the slope-intercept equation of the form y = mx + b, with m = 3/4 and b = 17/4:
y = mx + b
y = 3/4x + 17/4

A leaky bucket is an<em> </em><u><em>“open system.”</em></u> A tank with a secure lid, with no leaks, is a <u><em>“closed system.”</em></u> If you know how much water you put in a closed system, and how much water you take out, then you know how much water is in the tank at any given time.
