Choose the equations which have a greater rate of change than the graph.

NemiM [27]

Option C: $y=\frac{3}{10} x$ is the equation that have a greater rate of change.

Explanation:

From the graph the coordinates are (0,0), (20,6), (40,12), (60,18) and (100,30)

We need to determine the rate of change.

The rate of change can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the any two coordinates in the formula, we get, the slope of the equation.

Let us substitute the coordinates (20,6) and (100,30)

Thus, we have,

$m=\frac{30-6}{100-20}$

Simplifying, we get,

$m=\frac{24}{80}$

Dividing, we get,

$m=\frac{3}{10}$

Also, the y - intercept of the equation is $b=0$

The equation of the line becomes $y=\frac{3}{10} x$

Thus, the equation that has a greater rate of change is $y=\frac{3}{10} x$

Hence, Option C is the correct answer.

Alex and Juana went on a 50 mile canoe trip with their class. On the first day they traveled 21 miles. What percent of the total

ioda

If 50 miles, is 100%, what is 21miles off that in percent?
well $\begin{array}{ccllll}
miles&\%
\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
50&100\\
21&x
\end{array}\implies \cfrac{50}{21}=\cfrac{100}{x}\impliedby \textit{solve for "x"}$
