The general form of point-slope is y - y1 = m(x - x1)
IF you are looking for the value of the slope, then look no further than the number attached to the (x - x1) part of the equation. For example the formula
y - 2 = 3(x + 2), notice the number attached to (x + 2), the 3. This is value of the slope.

To tell how the line looks use this general statement
slope is positive - the line from left to right will go up
slope is negative - the line from left to right will go down
y = a number - this is a zero slope, so the line neither goes up or down
x = a number - this is an undefined slope, so the line goes straight up and down

To mix plaster for a dental model, 35 mL of water is used for 100g of plaster. How many mL of water should be used for 250g of p

laila [671]

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:

$\begin{gathered} \frac{x}{35mL\text{ of water}}=\frac{250g\text{ of plaster}}{100g\text{ of plaster}} \\ x=\frac{250g\text{ of plaster}}{100g\text{ of plaster}}\cdot35mL\text{ of water} \end{gathered}$

Solving for x:
