What information does a slope-intercept form equation give you?
Equations written in slope-intercept form follow a specific format.
y= mx+b
In this form, m represents the slope of the line and b represents the y-intercept.
Since the given equation is not in slope-intercept form, let's rewrite it so that it will be easier to identify the slope and y-intercept.
Below we highlight the slope m and y-intercept b. y= 6x+1 The slope is 6. The y-intercept is 1, so the graph crosses the y-axis at the point (0,1).
A slope of 6 means that for every 1 unit we move in the positive horizontal direction, we move 6 units in the positive vertical direction. m= 6/1 ⇔ rise/run=6/1 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
