Slope Intercept Form
The slope-intercept form of a linear equation is written as y = mx + b, where m represents the slope (how steep the line is) and b represents the y-intercept . This form makes it super easy to identify these key features at a glance!
When given an equation like y = 4/5x + 5, you can immediately tell that the slope is 4/5 (meaning the line rises 4 units for every 5 units it moves right) and the y-intercept is 5 . Similarly, in y = -3x + 17, the slope is -3 and the y-intercept is 17.
To write your own equation in slope-intercept form, just plug the values into y = mx + b. For example, if the slope is 1/2 and the y-intercept is 9, your equation would be y = (1/2)x + 9. If the slope is -4 and the y-intercept is 4, you'd write y = -4x + 4.
Quick Tip: Remember that a negative slope means the line goes downhill from left to right, while a positive slope means it goes uphill!
To graph a line using slope-intercept form:
- Plot the y-intercept on the y-axis
- Use the slope to find additional points
- Connect the points with a straight line
For example, to graph y = 2x + 3, start at the point (0,3), then use the slope of 2 to find more points by moving right 1 unit and up 2 units repeatedly.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
