The slope of a line measures its steepness. (either negative or positive)


The formula to calculate slope is #(y^2-y^1)/(x^2-x^1)#

Therefore, create a table of values for x and y to determine its points on a graph.

Two values that you should get would be (0,0) and (1,3).

Substitute the values in the equation above to obtain the slope of 3.

Slope (m) = 3


In order to find the slope of given equation, compare it with slope intercept form of an equation.

The slope intercept form of an equation is given by;

#y=mx+c# .......equation 1.
m = slope and c = y-intercept

Now we have;
#y=3x#...........equation 2

Compare equation 1 and 2, we get
m = 3 and c = 0

Hence, the slope of given equation is 3.
