5. Graphing Linear Equations in Slope-Intercept Form
Sign In
What information does a slope-intercept form equation give you?
x-intercept: 0
Graph:
Equations written in slope-intercept form follow a specific format. y= mx+ b Here m represents the slope of the line and b represents the y-intercept.
A slope of 5 means that for every 1 unit we move in the positive horizontal direction, we move 5 units in the positive vertical direction. m=rise/run=5/1 To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
Now that we have graphed the given function, we can use our graph to identify the x-intercept. This is the point at which the line intercepts the x-axis.
The line crosses the axis at (0,0), so the x-intercept is 0.
