Slope-Intercept form is an equation for a line that shows the slope and the y-intercept of a line. The y-intercept is where the line crosses the y-axis. The slope-intercept form is shown as [math]y=mx+b[/math], [math]m[/math] being the slope and [math]b[/math] being the y-intercept.

To find the equation of this line in slope-intercept form, we have to find the slope and the y-intercept. Since the y-intercept is where the a line crosses the y-axis, the y-intercept is at (0,3). Next, find the slope. Remember, the slope is the change in y over the change in x, or rise over run. the slope you should get is [math]\frac{4}{4}[/math] or 1. Now, put the value of the slope in place of [math]m[/math] and the y value of the y-intercept in place of [math]b[/math]. So now you have equation of the line in slope-intercept form: [math]y=1x+3[/math] or [math]y=x+3[/math].
