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= 32x+6
The slope is 32. The y-intercept is 6, so the graph crosses the y-axis at the point (0,6).
A slope of 32 means that for every 2 units we move in the positive horizontal direction, we move 3 units in the positive vertical direction. m= 32 ⇔ rise/run=3/2 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
