<span>The main difference between a mountain and a plateau is that the mountain is an elevated, pointed structure whereas a plateau is an elevated area with a flat top. A plateau is generally lower in height than mountain, though there are plateaus higher than some mountains.</span>
The values of k and b of this graph that passes through the given points is
and ![b = \frac{-50}{9}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B-50%7D%7B9%7D)
<u>Given the following points:</u>
- Points on the x-axis = (2, -7)
- Points on the y-axis = (10, -10)
.....equation 1.
To find the values of k and b since the graph passes through the given points:
First of all, we would determine the slope of the graph passing through the given points.
![Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=Slope.%20%5C%3Bm%20%3D%20%5Cfrac%7BChange%20%5C%3B%20in%20%5C%3B%20y%20%5C%3Baxis%7D%7BChange%20%5C%3B%20in%20%5C%3B%20x%20%5C%3Baxis%7D%20%5C%5C%5C%5CSlope.%20%5C%3Bm%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Substituting the points into the formula, we have;
![Slope. \;m = \frac{-10 - 10}{-7 - 2}\\\\Slope. \;m = \frac{-20}{-9}\\\\Slope. \;m = \frac{20}{9}](https://tex.z-dn.net/?f=Slope.%20%5C%3Bm%20%20%3D%20%5Cfrac%7B-10%20-%2010%7D%7B-7%20-%202%7D%5C%5C%5C%5CSlope.%20%5C%3Bm%20%20%3D%20%5Cfrac%7B-20%7D%7B-9%7D%5C%5C%5C%5CSlope.%20%5C%3Bm%20%20%3D%20%5Cfrac%7B20%7D%7B9%7D)
The standard form of an equation of line is given by the formula;
....equation 2
<u>Where:</u>
Next, we would determine the intercept of the graph:
![10 = \frac{20}{9}(2) + b\\\\10 = \frac{40}{9} + b\\\\b = \frac{40}{9} - 10\\\\b = \frac{40\; - \;90}{9}\\\\b = \frac{-50}{9}](https://tex.z-dn.net/?f=10%20%3D%20%5Cfrac%7B20%7D%7B9%7D%282%29%20%2B%20b%5C%5C%5C%5C10%20%3D%20%20%5Cfrac%7B40%7D%7B9%7D%20%2B%20b%5C%5C%5C%5Cb%20%3D%20%20%5Cfrac%7B40%7D%7B9%7D%20-%2010%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B40%5C%3B%20-%20%5C%3B90%7D%7B9%7D%5C%5C%5C%5Cb%20%3D%20%5Cfrac%7B-50%7D%7B9%7D)
The standard form of this equation of line is:
.....equation 3.
Comparing eqn 1 and eqn 3, we can deduce:
and ![b = \frac{-50}{9}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B-50%7D%7B9%7D)
Therefore, the values of k and b of this graph that passes through the given points is
and ![b = \frac{-50}{9}](https://tex.z-dn.net/?f=b%20%3D%20%5Cfrac%7B-50%7D%7B9%7D)
