Slope of table

  • (3,2)
  • (6,4)

Slope

  • m=4-2/6-3
  • m=2/3

Any equation having slope greater than 2/3 has higher unit rate than that of table

Answer:

Any equation with a slope greater than ²/₃

Explanation:

Given table:


\begin{array}\cline{1-2} x & y \\\cline{1-2} 3 & 2 \\\cline{1-2} 6 & 4 \\\cline{1-2} 9 & 6 \\\cline{1-2} \end{array}

The unit rate is a ratio that compares the first quantity to one unit of the second quantity. The unit rate is also the slope of a linear equation.

Linear equation


y = mx + b

where:

  • m is the slope
  • b is the y-intercept

To find the slope, take two ordered pairs from the table:


\sf let \: (x_1,y_1)=(3,2)


\sf let \: (x_2,y_2)=(6,4)

Substitute them into the slope equation:


\sf slope=(y_2-y_1)/(x_2-x_1)=(4-2)/(6-3)=(2)/(3)

Therefore, the unit rate is ²/₃.

Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
