What is the slope of the line described by the equation y3x

What is the slope of the line described by the equation y=3x + 5. What does the slope tell you about the relationship between x and y ?

Solution

The slope intercept form of the equation of a straight line is y = mx + c, where m is the slope and c is the y-intercept. Slope indicates the steepness of a line. The greater the slope, the steeper is the line. Slope = Vertical Change/ Horizontal Change.

The slope indicates the rate of change in y per unit change in x. Here, m = 3 so that the slope of the line is 3.Thus, for every one unit that x moves over to the right, y goes up by three units.
