1 Type in the equation of the line.
Give your answer in the form

To write the equation of a line in the form , you need to identify the slope (m) and the y-intercept ©. For example, if you have a line that passes through the points (2, 3) and (4, 7), you can first find the slope using the formula , which gives you . Using the slope and one of the points to find the y-intercept, you can form the equation .

Have fun experimenting with different points! For instance, if you have two points that create an upward slope, your line will rise from left to right. If you ever end up with a negative slope instead (like moving downwards), don’t worry – it simply means you’re charting a descent! Just remember to double-check your math to avoid common pitfalls like confusing your x and y values.
