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.
Below we highlight the slope m and y-intercept b.
A slope of - 34 means that for every 4 units we move in the positive horizontal direction, we move 3 units in the negative vertical direction. m=-3/4 ⇔ rise/run=-3/4 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
