A number y is 5 times the value of a number x. A line graphed in a coordinate plane represents the relationship between x and y. What is the slope of the line?

The slope of the line is five (5).

Given the following data;

  • y = 5x

To find the slope of the line;

We know that the line graphed on a coordinate plane is represented by the relationship between x and y.

Also, we can deduce from the sentence that the value of y is increased by 5 whenever there is an increase in the value of x.

Thus, when;

  • [tex]y_1[/tex] = 5, [tex]x_{1}[/tex] = 1
  • [tex]y_{2}[/tex] = 10, [tex]x_{2}[/tex] = 2.

Mathematically, the slope of a line is given by the formula;

[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substituting the points into the formula, we have;

[tex]Slope. \;m = \frac{10 - 5}{2 - 1}\\\\Slope. \;m = \frac{5}{1}\\\\[/tex]

Slope, m = 5

Therefore, the slope of the line is five (5).
