We can highlight the slope m and y-intercept b of our equation so that it will be easier to create the graph.
y= 2x + 6
The slope is 2 and the y-intercept is 6.
Graphing the Equation
A slope of 2 means that for every 1 unit we move in the positive horizontal direction, we move 2 units in the positive vertical direction.
m=rise/run=2/1
To graph the equation, plot the y-intercept and then use the slope to find another point on the line.
Identify the x-intercept
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 (-3,0), so the x-intercept is -3.
